André Luiz A Silveira

I'm a senior full-stack engineer with 7 years of experience building web applications and backend systems that companies rely on in production — not prototypes that get thrown away.

What I build:
- Backend services and APIs in Go and Python (REST, gRPC, async pipelines)
- Web applications in React/TypeScript, from dashboard to full product
- PostgreSQL data modeling, query optimization, and migrations on live systems
- AI/LLM integrations: RAG pipelines, agent workflows, and LLM-powered features wired into real products

How I work: I start by understanding the business problem, propose a clear scope with milestones, and deliver in reviewable increments: you see working software every week, not a big reveal at the end. Code comes tested, documented, and ready for handoff.

Good fits: building a product from scratch, extending or refactoring an existing codebase, adding AI features to your product, or rescuing a project that stalled.
