Building intelligent systems at the intersection of web development, machine learning, and Industry 4.0.
About
I'm a developer based in Manaus, Brazil. I like building things that are both useful and well-crafted — from real-time dashboards and production tools to computer vision pipelines and web applications.
I currently work in the industry side of tech, which has given me a taste for systems that need to be reliable, fast, and meaningful to the people who use them every day.
Before that, I led and contributed to web projects at companies like Compass UOL, FITec, and Mobister, growing from front-end developer to tech lead. I'm drawn to the intersection of AI, modern web, and real-world engineering problems.
Lately I've been deep into the AI agent space — LangGraph, LangChain, open source models, fine-tuning, MCP servers, and prompt engineering. I find the challenge of making agents that actually work in production genuinely interesting.
Currently deepening my expertise through a postgraduate degree in Data Engineering & AI. When not coding, I'm exploring new models, experimenting with agentic workflows, or thinking about how technology can genuinely improve people's lives.
