Summary
Guillaume Becker is a Senior Software Engineer and Frontend Lead with 11 years of experience building web products across air quality monitoring, fintech and blockchain domains while based in Seoul. He combines hands-on expertise in modern front-end stacks (React, Next.js, TypeScript) with infrastructure fluency across Cloudflare, AWS, serverless platforms and CI/CD, enabling fast, resilient delivery. A self-taught polyglot developer grounded by a Master’s in Computer Science from EPITECH, he routinely bridges front-end engineering, product processes (Scrum/Kanban) and team mentoring. His track record spans leading frontend teams at startups and scale-ups like Awair, Korbit and Glassdome, where he focused on shipping user-facing systems that integrate with complex back ends and real-time data. Known for pragmatic ownership, he also brings backend experience in Node, Rails, GraphQL and Go, which helps him architect full-stack solutions rather than isolated UI components. Unusually for a lead frontend engineer, his background includes hands-on roles from backend development to operational tooling, reflecting a broad, end-to-end engineering mindset.
