What I'm looking for

I'm looking for a collaborative environment that fosters growth and innovation.

Software Engineer with experience building production systems for finance, AI, and data-intensive applications. Currently at BTG Pactual, where I modernize core middle-office platforms using NestJS, Golang, DDD, and Clean Architecture, while maintaining large-scale financial pipelines. I also design and deploy agentic AI systems — including Text-to-SQL and analytical assistants — that enable non-technical teams to interact with data autonomously.

Across my work, I combine strong backend engineering (Golang, NestJS, PostgreSQL, AWS) with AI tooling (RAG, LangChain, LLMs, vector databases) and modern frontend development (React/Next.js). I favor modular design, clear domain boundaries, and pragmatic, production-first solutions.
