What I'm looking for

I'm looking for a remote senior individual-contributor role where I can own careful, maintainable Rails and React changes in mature production systems, collaborate with LATAM or international teams, and solve complex business workflows involving data, APIs, search, and reliability.

I maintain and enhance high-traffic Ruby on Rails media platforms at SK Intertainment, investigating production issues across SQL, ActiveRecord, search indexing, deployments, and customer-facing workflows. I build maintainable full-stack features while balancing product requests with regression risk and production reliability.

Across Pozool, MOi Solutions, MERCON Coffee Group, and financial and customs systems, I've delivered Rails, React, Java, and PostgreSQL solutions for operationally complex products. I bring 10+ years of experience in backend architecture, APIs, search and retrieval, reporting, RBAC, and remote collaboration with LATAM and international teams.
