Summary
👤
Senior🎓
Top SchoolJavier Germán is a Technical Lead and seasoned frontend engineer with 11 years of experience building customer-facing web and mobile products, currently based in Amsterdam. He blends hands-on development (React, Next.js, React Native, Typescript) with architectural and process leadership, having shipped multi-tenant, multi-language advertising platforms and an EdTech product used by business schools. As a freelancer and founder of Rockman Software he accelerates teams through modern stacks, testing, CI/CD and pragmatic AI-assisted workflows. He has deep experience integrating complex systems—SSO, LTI for LMS, serverless audio generation with Google TTS and AWS Lambdas—so he’s comfortable connecting frontend UX to backend services. Colleagues rely on him for mentorship and knowledge sharing, and less obviously he pairs startup agility with enterprise-grade delivery learned across telecom, finance and adtech teams.
