What I'm looking for

I’m looking for roles where I can own high-reliability backend systems in fintech, work with distributed teams on AWS/Azure microservices, and apply AI-driven tooling to ship faster without sacrificing code quality.

I build backend systems that hold up under pressure, with 6+ years of experience focused on scalable microservice architectures, event-driven systems, and serverless infrastructure on AWS and Azure.

My background is heavily fintech: I’ve shipped zero-downtime migrations of mission-critical financial platforms, built high-volume transactional pipelines, and maintained 99.9%+ uptime for systems managing millions of records. I apply clean architecture and TDD principles across distributed systems, prioritizing reliability, maintainability, and thoughtful engineering decisions.

I’m also deeply invested in AI-driven development, integrating OpenAI APIs and building multi-agent workflows while using Claude Code and GitHub Copilot to accelerate delivery without sacrificing code quality. I enjoy owning projects end-to-end—from architecture design through deployment and monitoring—and collaborating effectively across US/LATAM teams.
