Senior Backend Engineer at Belong · São Paulo, Brazil · GMT-3
I build scalable distributed systems and backend infrastructure in .NET / C#, design event-driven microservices, and integrate AI/LLM workflows into production environments. Currently working remotely with a US engineering team on a property management platform serving thousands of users.
Strong believer in clean architecture, clear code, and systems that are simple to operate.

- Distributed backend systems — microservices, event-driven architecture, CQRS, DDD
- AI/LLM integrations — production pipelines with OpenAI, prompt engineering, LLM observability
- System modernization — migrating legacy monoliths to scalable cloud-native architectures
- Fullstack features — end-to-end ownership from API design to React and Angular frontends
- Production reliability — observability with Datadog & Sentry, dead-letter queues, retry strategies
A practical implementation of Clean Architecture in .NET / C# based on Robert C. Martin's book. Demonstrates layered separation of concerns, dependency inversion, and testable application design.
C# .NET Core Clean Architecture DDD
A To-Do API built with Node.js and TypeScript applying Clean Architecture principles — InversifyJS for IoC, ExpressJS for routing, fully structured for testability and maintainability.
