I build AI-powered
products.
I'm Pedro - a backend-focused software engineer and tech lead in Leiria, Portugal. Ten years shipping production web apps; right now leading a small team and building LeiGo on the side.
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.

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.
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.
