software engineer — building full-stack platforms and production AI agents for small businesses.

joão pessoa, brazilopen to work anywhere — remote or relocation

software engineer who builds end-to-end web platforms, APIs, cloud, and the AI/ML that ties them together. right now i'm shipping production AI agents, but i'm just as at home in a React frontend, a Python backend, or a model. i learn fast, like real ownership, and care about code that works in production.

featured projects

a few things i've built end-to-end, from the model layer to the api.

LawSense

2026 — Present

a conversational assistant for Brazilians with low digital literacy, built on a REST API and a structured prompt system. i ran a systematic evaluation of Gemini vs. Llama 3.3 (Groq) on quality and latency, then migrated the production provider based on the results.
