Why most software fails

It's rarely the code. It's the fit.

Across decades working inside real operations — footwear, electronics, kitchenware, metallurgy, defense — I kept seeing the same pattern: software fails not because of bad engineering, but because the people building it never understood the data or the process underneath it. Standard software is standard. Fitting it to how a business actually runs rarely is.

How I work
01
Diagnose
Map the real process, not the one on paper.
02
Redesign
Fix the process itself, not just the symptom.
03
Build
Apply AI only where it earns its place.
Proof
The problem

A multi-location service network was losing time and accuracy to manual, duplicated data entry at reception — every unit doing it differently.

What I built

An AI-assisted intake system deployed across multiple locations, extending into WhatsApp for client communication, with a human-approval checkpoint before anything reaches the client.

The result

Consistent process across every location, less manual entry, faster response times — without removing human oversight from anything client-facing.

What I bring

More than 40 years in industrial operations — always in charge, never as an outside consultant. These are the results I've delivered, organized by the kind of problem they solve:

Cost reduction and process efficiency

Eletrônica Selênium — cut material costs through supplier development and production process optimization (automation, faster changeovers); built an automated speaker assembly line manufactured in Japan; the restructuring ended in the company's sale to the Harman Group, owner of JBL. Medabil Tessenderlo — cut changeover time, opening up a market segment that had been out of reach before.

Structuring product development

Digitel — implemented a structured product development process where none had existed before, replacing a pattern of defects and late launches; transferred technical know-how in thermoplastic materials. Sports footwear manufacturer (1,000+ employees) — structured product launch process that drastically cut time-to-market; complete operational diagnosis in 60 days.

Crisis management and recovering a strategic client

CBC — Companhia Brasileira de Cartuchos — restructured the U.S. export line, recovering the relationship with Mossberg.

Reference-grade technical training

Philips do Brasil — technical training at the world's largest electronics multinational; first Brazilian designer to represent the country at the Eindhoven headquarters. Zivi Hércules — product development in the metalworking industry.

MBA in Business Process Management from Fundação Dom Cabral. Today I apply that same operational lens to building the systems myself — Next.js, Vercel, Supabase, AI integrations.

What I've built

I don't just advise — I ship. These are products I designed and built end to end.

What I'm looking for

As a consultant, I look for one kind of problem: operations that need to run better — faster, cheaper, more consistent, higher quality — where the fix requires actually understanding the process before touching any technology.

My way in is always the same: diagnose the real process, redesign what's broken, then apply AI wherever it earns its place — never AI for its own sake.

If any of that sounds familiar, that's the conversation I want to have.
