Full Stack Developer · Dominican Republic

Building production-grade web applications with modern architecture, test-driven development, and AI-assisted workflows.

Senior-minded developer focused on shipping reliable software. I design systems that scale, write tests that catch regressions before they hit production, and leverage AI tooling to maintain velocity without sacrificing quality.

Core philosophy: Clean architecture, comprehensive testing, and continuous delivery are not optional — they are the baseline for professional software development.
