Full-Stack Engineer& AI Analyst
About me
Origin story
My journey in programming began at 16, during high school, when I won a scholarship at Fucapi. Being among the top 50 grades led to my first practical, paid experience: developing a school management system for remote communities in Amazonas. This early start shaped my drive to use technology to solve real-world problems.
Current chapter
Today, I'm a Full-Stack Engineer & AI Analyst with 5+ years of experience. At Positivo Tecnologia, I single-handedly built an AI-powered document analysis service that cut government contract review from 1-2 weeks to ~5 minutes per case with ~90% accuracy, enabling a team of 6 analysts to focus on higher-value work.
Technical expertise
On the front-end I build with React and Next.js. On the back-end, Node.js, NestJS, and Fastify. On the AI side, I work with Python, LangChain, and Pydantic to create production AI workflows — from PDF preprocessing pipelines to agent-based document processing with async orchestration via Celery and Redis.
What drives me
I turn slow, manual processes into fast, reliable products. Whether it's building AI workflows that automate complex analysis or shipping e-commerce platforms from scratch, I thrive at the intersection of Artificial Intelligence and Software Engineering.
