01About

Ten years of backend, now leading on AI.

I'm a backend-focused software engineer and tech lead. For the past two years I've led a small engineering team, designing and building a multi-tenant LLM-powered WhatsApp customer support platform on Google Cloud - per-tenant config, RAG, supervisor LLM agents, the whole stack.

Before that I spent 5+ years delivering configurable Java platforms for the banking sector. On the side I'm building LeiGo, a RAG chatbot over Portuguese legislation.

04What I do

What I spend my time building.

Product engineering

End-to-end product builds - web and mobile, backend-first, shipped and maintained in production.

AI integration

Practical LLM features that hold up in production: retrieval, evaluation, guardrails, latency. Less demo, more durable.

05Get in touch

Open to OpenSource
Knowledge is power

Always happy to talk backend, AI products, or open source - whether it's something I'm building or something you are. Email's the fastest way to reach me.
