About this gig

Are you looking for a backend engineer who actually ships production-ready systems?

I build Go and TypeScript backends with 5+ years of experience including systems that processed 6M+ daily requests at Nike Brazil and AI-powered products using Claude API, RAG pipelines, and agentic workflows.

What I can build for you:

- REST APIs in Go (Gin + GORM) or TypeScript (NestJS / Express)

- AI integrations Claude API, RAG, agentic workflows, LLM orchestration

- PostgreSQL / MongoDB data modeling and optimization

- JWT authentication and role-based access control

- Cloud deployment on Railway with CI/CD

- Performance optimization and legacy refactoring

All my projects are deployed and running in production I don't just write code, I ship products.

Why hire me?

I use Claude Code as my primary development workflow, which means faster delivery without cutting corners. Senior-level engineering, startup speed.

Drop me a message before ordering if you want to discuss your project first. I'm happy to help you scope it correctly.
