— EXPERTISE
Domains I have delivered in.

05 · BIOMETRICS & SECURITY

06 · ERP & ADMIN

— ABOUT
20+ years. Direct with who builds.
Software engineer with over two decades developing and integrating systems — from cooperatives and distributors up to mission-critical work at high-scale marketplace (Mercado Livre, First Party). I now bring that depth to small and medium businesses with the same engineering seriousness as an enterprise operation.
See full track record- 01 Direct support with the developer — no middlemen, no management layers.
- 02 AI as copilot: shorter cycles, more delivery, same engineering care.
- 03 Every change is reviewed and tested before going live — quality is not optional.
- 04 Clear specification before code. You know what is coming, and when.
- 05 Scope, deadline and budget in writing before kickoff.
