Summary
🤩
Rockstar🎓
Top SchoolRaphaël Badia is a seasoned engineering leader with 13 years of experience building scalable web and mobile platforms for fast-growing startups, most recently driving tech at Billiv as Tech Lead. He combines hands-on frontend expertise (component libraries, React/React Native, server components) with system-level improvements—monorepos, CI pipelines, i18n per-component, E2E testing—that repeatedly unlocked multi-million user growth and international expansion. At Maiia he scaled the platform from 500k to 3.25M users, instituted testing culture, and led cross-functional teams through high-stakes government-driven features. Comfortable across the stack, he has shipped desktop proxy software, wallets passes, omnichannel plugins and CMS-driven marketing sites while also mentoring and recruiting engineering teams. Known for pragmatic architecture and developer experience improvements, he often surfaces non-obvious wins like translating UI components into a reusable component library that prevented thousands of bugs before demo. Based in Paris, he blends product-minded engineering with operational rigor to turn complex requirements into production-ready, customer-facing systems.
