How much does a custom software system cost?

It depends on what the system has to solve, which is why I don't work from a price list. What I do guarantee is the format: a fixed price per project, set after the diagnosis, with no perpetual monthly license and no charge per user. You know the total before we start.

How long until I see something working?

The work runs in short cycles, with deliveries you use from the first weeks instead of months of silence leading to one big reveal at the end. The full timeline comes out of the diagnosis, along with the scope. I have delivered in two months a production system that the conventional route would have taken at least six.

Do you work with companies outside Sorocaba?

Yes. My base is Sorocaba and on-site work covers the region, from Votorantim to Itu, but most of the work is remote and I serve companies anywhere in Brazil. Diagnosis and factory rollout usually call for being there in person; the rest doesn't.

Do I have to replace my ERP to connect the shop floor?

Almost never. Replacing or restructuring the ERP is the expensive, slow, risky way out, and it tends to be the first thing you get offered. I build a satellite system that talks to the ERP you already have: the operation stays on its feet during the work and the timeline drops from months to weeks.

Can you connect a machine, PLC or microcontroller to the system?

It's one of the things I do most. Sensors, controllers and equipment delivering data straight into the web application, in real time, with history stored for analysis. That's what separates a pretty dashboard from a real supervisory system.

Do you build company websites and landing pages?

I do, and I treat them as a sales channel: structure the search engine understands, content that answers what the customer is looking for, and the inquiry landing straight where your team answers. If the goal is just a pretty page, with no function, there are cheaper options than me — and I'll tell you that instead of selling you what you don't need.

Do you develop mobile apps?

Yes, for Android and iOS, always connected to the same base as the system running in the browser. An isolated app, one that doesn't talk to the rest of the operation, is just one more island of data, and islands of data are exactly the problem I solve.

Do you take on product management or only development?

I take it on. Discovery with the people who use the system, prioritization by impact, roadmap and follow-through to delivery, with your internal team or in place of it. It's the product manager role performed from the outside, with the difference that I also build what I prioritize.

Do you work alone or with a team?

Alone on most projects: it's what keeps the technical decisions coherent and the price honest, with no layer of people relaying messages. On large projects I bring in developers under my management, and responsibility for the delivery stays mine.

My current system is old. Can it be reused?

Almost always. A legacy system usually holds valuable business rules trapped in bad code, and throwing it all away means losing years of knowledge with it. I go into it, work out what it does and modernize it in stages, with the operation running during the swap.

Is it worth putting artificial intelligence in my system?

Where it pays for itself: classifying, predicting, drafting and flagging the exception before it turns into a problem. AI put in because it is in fashion produces a bill at the end of the month and no result. If that's your case, I'll say so before you spend.

What happens after the system goes live?

Server, backup, monitoring and fixes stay with me. You don't need to hire an IT company to maintain what I delivered. If you want continuous evolution, there is monthly follow-through proportional to the service, never an inflated subscription that follows you for the rest of your life.

Systems Consultant in Brazil · Web Solutions

André Franceschini — software consultant based in Brazil: custom systems, systems integration and apps that fix your company's operation.

Systems that solve. Interfaces that impress.

[ Real-time supervisory systems ]

scroll ↓full-stack · web · real time

Your company doesn't have a technology problem.

It has systems that don't talk.

Processes trapped in spreadsheets.

Data nobody can see.

I understand the operation in full and build the system that solves it.

01 / The thesis

Satellite, not demolition.

What already works stays standing. I build around it, connecting every edge to the center in real time.

02 / What I build

From database to pixel.

ASystems & integration

The core: making what exists talk, and building what's missing.

Custom-built systems

The system grows out of your operation, not the other way around. A complete solution, delivered in production and working, never half a system waiting on a second vendor.

Systems integration

ERP, shop floor, bank, spreadsheet, legacy: each one speaks its own language. I get them talking through a single source, with the same number holding true across the whole company.

One portal for the company

One address, one login, every department in the same place. Each person reaches exactly what their role allows, and nothing beyond it.

Legacy rescue

The old system nobody dares touch, inherited from someone who has already left. I go into it, work out what it does and modernize it in stages, without interrupting the operation.

BReal-time operations

Data leaving the place it happens and reaching the person who decides.

Real time, for real

What happens on the machine, on the order and at the register shows up on screen the moment it happens. Management stops discovering the loss the next day.

Machines that talk to the system

Sensors, controllers and microcontrollers wired straight into the web application. Data leaves the equipment with no clipboard, spreadsheet or typing along the way, with the history recorded.

Routine automation

The repetitive work that consumes your team (checking, typing, chasing, notifying) starts running on its own, pulling in a person only when something falls outside the pattern.

Data & decisions

Your numbers live in five places and become a spreadsheet assembled by hand before every meeting. I consolidate them into one dashboard that updates itself and surfaces what requires a decision.

CReach & revenue

The system reaching your customer and turning into revenue.

An app for the phone

The system in the pocket of whoever works outside the office: the technician in the field, the rep on the road, the operator on the line. Android and iOS on the same base, never an isolated island of data.

A site that brings customers

Website and landing page as a sales channel, not a business card: structure the search engine understands, content that answers what the customer is looking for, and the inquiry landing where your team answers.

Recurring revenue

What you sell today becomes a digital product: a catalog with pricing calculated by the system, subscription and billing automated, every cent recorded and auditable.

Applied artificial intelligence

AI where the return is concrete: predict, classify, draft and flag the exception before it turns into a problem. Never for the hype.

DSupport & direction

What keeps the system standing and the project on course.

System live

Server, security, backup and monitoring under the responsibility of whoever built it. You don't hire one more IT company to maintain what I delivered.

Security & access control

Who sees what, who changed what and when. Role-based access, an audit trail, tested backups, and the technical side of GDPR and Brazil's LGPD resolved from day one.

Product management

Some projects don't need one more programmer, they need someone to decide what gets built first. Discovery, prioritization by impact and follow-through to delivery.

The face of your company

An internal system doesn't have to be ugly. Your identity respected, an interface the team uses with pride and that holds up when the customer sees it too.

/ Diagnosis

The symptom is visible.
The cause, almost never.

Systems consulting is not selling software. It is seeing the whole operation, finding where it jams and building exactly what solves it.

/ The contrast

A giant consultancy is no guarantee of a solution.

You've already paid dearly to be told the problem is your operation. What if the problem is the system?

✕ The usual consultancy

License + rollout + consulting hours: the numbers never add up
A generic solution: your operation is what has to adapt
The proposed way out is restructuring what already works: months and risk
Months of meetings before the first working screen
Whoever sells it is not whoever builds it
Big promise in the contract, small validation in practice
Support by ticket, queue and escalation

✓ With me

Fair project pricing, with no perpetual license locking you in
A satellite system: I integrate with what exists instead of tearing it down
Fast delivery, working within the first weeks
Custom-built: the system grows out of your operation
AI first, with prudence, where it produces a real result
Follow-through with real checkpoints at every stage
I only take the project when the result is possible, and then I commit to it

You don't need the biggest consultancy. You need the right solution.

03 / Projects

Real systems, running in real companies.

R$ 250K+

≈ $47,989 · rate of 2026-08-19

saved on industrial systems built as satellites of what the company already had, instead of restructuring what already worked.

6 months → 2≈ $23,995: A production system that would have required restructuring the ERP and at least six months went live in two. Around R$ 125,000 saved in development.
R$ 50K≈ $9,598: Operational processes standardized with digital records and traceability, shifting corrective maintenance into preventive. Savings estimated by the operation itself.
Telemetry: Assets instrumented with consumption anomaly detection: the deviation is caught the moment it occurs, not at month-end close.

01Corporate ecosystem

Industrial Portal

Manufacturing industry · 5+ systems · universal SSO · real time

✕ The problem

The operation was tracked across spreadsheets and separate systems: machines with no visibility, indicators assembled by hand before every meeting, uncontrolled access and each department sitting on its own island of information.

→ The solution

A single portal with its own SSO authentication pulling several systems together: real-time supervisory view per production line over WebSocket, a synoptic panel of the process, KPIs with action plans and a presentation mode for meetings, admin modules with group-based access control, file management and an activity trail.

✓ The result

Standardized operational processes and incident logging consolidated in the same portal: the deviation is captured where it happens and becomes traceable history, shifting rework, scrap and corrective maintenance into preventive action.

The whole plant at one address, behind one login.

02ERP + shop floor integration

Production System

Manufacturing industry · 6 months → 2 months · R$ 125,000 saved

✕ The problem

Two sources of truth that never spoke to each other: the ERP holding the schedule and production reporting, and the shop floor supervisory system holding batches, loads, downtime and losses. Between them, paper, typing and delay.

→ The solution

A gateway that consolidates both sources into a single API and hands the operator one simple screen on the shop floor: the production order front and center, weighing posted straight into the ERP, profiles by access level (operator, lead, admin). A frontend with no framework, light enough to run on any terminal in the plant.

✓ The result

The obvious route was to restructure the ERP: at least six months, high cost and the risk of halting the operation during the swap. The satellite system went live in two months, integrated with the ERP instead of replacing it, and saved around R$ 125,000 in development.

What happens on the machine reaches the ERP right away, with no paper in between.

03Microcontrollers + web

Industrial Telemetry

Manufacturing industry · field → web · baseline anomaly detection

✕ The problem

Utility consumption was only known at month-end close, from the invoice. Deviations and waste ran for weeks with no detection at all, and the only possible response was paying a difference already spent.

→ The solution

Meters instrumented with microcontrollers and integrated into a web application: continuous readings coming off the field, history persisted and compared against the consumption baseline to expose the anomaly. When the curve drifts from the pattern outside the production window, the system flags the event instead of waiting for the close.

✓ The result

Consumption anomalies identified and handled from the field data itself, avoiding losses that used to surface only in the invoice.

The asset warns you before the loss, not after the bill.

04Own product · from zero to subscription

SaaS Platform

Own product · live · 8 API domains · recurring payment

✕ The problem

Every business that sells a service hits the same ceiling: manual math, an improvised catalog, pricing by guesswork and revenue that depends on chasing one customer at a time.

→ The solution

A complete platform that closes that loop: a cost and pricing engine running on the server, a white-label storefront carrying the client's brand, a reseller network with commissions and statements, a community, a course track, recurring subscription with automatic payment, plus an admin with moderation, auditing and a security center.

Turning a service into a digital product with recurring revenue: a cycle I know end to end, because I lived every step of it.

Financial Platform

Own product · live · 30+ backend modules · applied AI

✕ The problem

Financial data scattered across banks, brokerages, cards and spreadsheets, with no whole picture, no forecast, and decisions made in the dark. The same drama as any company's finance department.

→ The solution

A platform with Open Banking connecting accounts and investments straight from the banks, an AI core classifying transactions and generating suggestions, cash projections, income analysis, goals and automatic notifications over WhatsApp. More than 30 backend modules running together.

Connect the data, apply AI and automate finance: engineering that serves your operation too.

04 / Opportunities

What this unlocks in your business.

Technology isn't the goal. What it does for the operation is what counts.

Your operation warning you when something jams

Machine down, order late, target blown: the system warns you right away, before the loss happens.

The end of double entry

What goes into one system shows up in the others. Nobody retypes an invoice, an order or a spreadsheet, and nobody mistypes one either.

Your numbers live, without asking for a report

Sales, production, cash: dashboards that refresh themselves, on the screen of whoever decides. The meeting starts with the number already there.

Your customer buying through your link

A storefront with your brand and pricing calculated by the system, with no table errors. The order lands straight in your WhatsApp.

Automated recurring revenue

Subscription, billing and commission running on their own, with every cent recorded. You watch, the system executes.

Your finance connected to the bank

Statements and investments flowing into the system by themselves, AI classifying the transactions and projecting cash for the months ahead.

Customer service that answers on its own

WhatsApp wired into the system: order status, alerts and automatic replies, without one more person copying and pasting.

System live, without the IT worry

Server, security and backup handled by whoever built the system. You don't need to manage one more IT vendor.

05 / Process

No canned formula. With method.

Diagnosis

Before writing code, I understand the operation. The real problem is almost never the one showing up as the symptom.

Architecture

I design the whole solution: data, integrations, screens and who accesses what. Nothing is born improvised.

Build

Short cycles, with working deliveries from the first weeks, no long stretches of silence.

Evolution

A system in production is a living organism: I monitor it, adjust it and evolve it alongside the operation.

/ How to hire me

one-off

Diagnosis

A short immersion into your operation: I map where the system blocks the business and hand you a clear plan of what to fix first, even if you don't carry on with me.

full solution

Fixed-scope project

Scope defined, delivery defined: I build the complete solution, deploy it to the server, train the team and leave it running. On large projects, I bring in a team of developers under my management.

monthly

Ongoing consulting

Me as your company's technical arm: I evolve the systems, guide technology decisions and back up your internal team, without you having to build an IT department.

A monthly fee, here, exists for two things only: periodic maintenance or close follow-through. Price proportional to the service, never an inflated subscription that follows you for the rest of your life.

06 / Who you're hiring

Fixed scope, your code, everything documented.

What usually gets asked before signing, answered before the question.

Engagement

B2B

A registered company, a contract and an invoice. Scope and price closed before we start, with no employment relationship and no middleman in between.

Ownership

Yours

The code, the repository and the credentials are registered to your company. No monthly licence to use what you paid for, and no dependency on me to get access.

Continuity

Handover

Decisions recorded, architecture written down, access handed over. If I step away, your team or another supplier picks it up where it stopped, without archaeology.

Reach

Remote

I serve companies in Brazil and abroad. Factory rollout needs presence; the rest is remote, on an agreed time zone.

Languages and mobility

Portuguese and English

I talk straight to your Brazilian team, to the machine vendor and to the local integrator. No interpreter sitting in the technical meeting, and no waiting on a translated manual to unblock the integration.

European citizenship

An EU passport. Factory acceptance at the vendor's plant, a meeting at head office or a rollout at a European site happen with no work visa and no authorisation deadline to sort out first.

Business travel

Diagnosis, kickoff and factory rollout happen on site when the project calls for it, in Brazil or abroad. Travel is agreed into the scope up front, it doesn't show up on the invoice later.

My companies

I built both from scratch and run them myself, live every day. Go in and see them working: architecture, product and infrastructure to the same standard I apply on client work.
