Senior Full-Stack Engineer (Rails + React)

About me

Ruby on Rails engineer with 7+ years of experience building and improving production applications across healthtech, ecommerce, edtech,
and startup products. I work mainly on Rails backends, PostgreSQL, GraphQL, APIs, performance optimization, data migrations, and legacy
modernization. I have worked across both full-time and contract roles, including owning backend systems end to end and shipping features
in existing large codebases. I am looking for remote product teams that value strong execution, clean code, and practical problem
solving.
