Summary
👤
Senior🎓
Top SchoolRafał Augustyniak is a Senior Software Engineer with over a decade of front-end focus and eight years of documented professional experience building high-traffic Node.js services and single-page applications. He’s a Micro Frontends practitioner who helped architect and maintain fragment-serving backends and developer tooling at scale for Allegro, and later optimized performance and migrations at Fandom. Comfortable across Angular, React, Vue and vanilla JS, he pairs hands-on implementation with performance engineering (Core Web Vitals, monitoring, CPU/memory optimization) and strong test discipline. He also builds hybrid mobile apps, teaches front-end curricula, and regularly runs interviews and internal training sessions, so mentorship and knowledge-sharing are part of his routine. Based in Masovian Voivodeship, Poland, Rafał enjoys tackling cross-cutting architecture problems that sit between UX, performance and operational stability. A less obvious strength is his track record of creating reusable tooling and workflows that empower independent teams to ship Micro Frontend fragments reliably.
