Production numbers, not pitch-deck numbers.
where I come in
Data turns into several versions of the truth and nobody answers a simple question without stopping their day.
What I deliver
Tailor-made CRM and ERP: pipeline, support, orders and finance in one place, with a decision panel.
You know what you want to build, but you're missing someone to handle the technical side — from the first draft to a live product.
What I deliver
A web or SaaS product that starts small, goes live early and grows backed by numbers.
Copy, paste, check, approve. The same manual work every day, with a chance of error at every step.
What I deliver
Automations and AI agents for the repetitive part — the doubtful case always goes back to a person.
selected work
A sales app that runs inside the card machine itself: menu, checkout, printed receipt, protected refunds and event pricing.
See case
Management system built from scratch: intake funnel, support, team and economy across 10 decision areas, with period deltas and permission-gated access.
signups in the funnel
120k+
See case
One link turns a cheating suspicion into recorded video, watched live by the staff and stored safely, even if the player closes the screen halfway.
See case
An AI agent that reads entry forms, produces a score and decides approval — with a human fallback when the case is ambiguous.

A store for GTA:RP and Minecraft servers with direct in-game integration, a config panel and automated tax-invoice issuing.

Who takes care of your project
Full-stack software engineer · São Bernardo do Campo, Brasil
I'm a full-stack software engineer based in São Bernardo do Campo, Brazil. I help companies and founders get web products, tailor-made business systems (CRM and ERP), automations and AI systems off the ground and keep them running in production with thousands of concurrent users. I handle everything, from the first idea to a product that's live and monitored, so you can watch the results, not the code.
If that's your case, no worries: I'll point you to the right person for it.
common questions
It depends on the scope — that's what the free diagnosis is for. You leave the conversation with a fixed scope, timeline and price, before any commitment.
No. I handle all the technical side; you follow the results, not the code.
Yes: legacy ERP, e-commerce, payment gateway, WhatsApp and the spreadsheet you already have. No typing the same information in two places.
It stays live and monitored, with post-launch support. Every improvement is measured before and after, so you see exactly what changed.
I'll tell you quickly and, when I can, point you to the right person for it.
