Summary
👤
Senior🎓
Top SchoolEfrain Castilla is a Senior Frontend Engineer with a decade of hands-on experience building user-focused web applications and shipping production React and NodeJS features at companies like ABOUT YOU and EPAM NEORIS. He pairs strong frontend craft (React, Typescript, StyledComponents, MaterialUI) with backend sensibilities (Django, Laravel, SQL), enabling him to own features end-to-end and collaborate on gRPC/protobuf integrations. A self-taught problem-solver who rose from an apprentice in a small agency to lead projects and close international SaaS deals, he brings practical product and project-management experience uncommon in purely technical engineers. Efrain’s MSc with distinction from the University of Glasgow and history of onboarding and documenting best practices reflect his commitment to continuous learning and team enablement. Based in Barcelona, he looks for roles that challenge his creativity and reward impact across both frontend and backend domains.
