# Leonardo Teixeira

Senior backend-focused full-stack engineer based in Brazil. I build reliable products end to end with Go, .NET and TypeScript.

## About

I work across domain modeling, APIs, data, messaging and modern web interfaces.

I care about modular design, explicit contracts, idempotent workflows and observable systems.

I use AI on both sides of the work: coding agents steered by specifications to build software, and LLMs, retrieval and agent workflows as parts of the product.

## Projects
