What I'm looking for

I am looking for senior full stack engineering roles where I can stay hands-on across TypeScript, React, Node.js, Go, AWS, Kubernetes, distributed systems, reliability, and AI-assisted engineering. I am focused on international remote teams building reliable products at meaningful scale, not people-management-only roles.

Senior Full Stack Engineer / Tech Lead with 20+ years building, modernizing, and scaling production software across fintech, gaming, retail, ticketing, SaaS, and enterprise systems.

I work hands-on across TypeScript, React, Node.js, Go, AWS, Kubernetes, distributed systems, APIs, reliability, observability, security, and cloud-native delivery. My experience includes platforms processing BRL 1B+ in PIX transactions, 100M+ retail users, and 2M+ daily gaming transactions.

I have led modernization from monoliths to microservices, cloud migrations, CI/CD, infrastructure as code, SLO/SLA improvements, and production reliability initiatives while staying close to implementation through architecture decisions, code reviews, mentoring, and delivery work.

I use AI-assisted engineering professionally with tools like Claude Code, Cursor, Codex CLI, OpenAI SDK, Vercel AI SDK, and LangChain to accelerate development, code review, debugging, test generation, documentation, product validation, and agentic system design, with senior engineering judgment validating every output.

I am open to remote international senior full stack engineering roles across North America, Europe, Latin America, and Asia-Pacific, collaborating in English, Spanish, or Portuguese.
