Summary
👤
Senior🎓
Top SchoolSebastian Rachfał is a Tech Lead and full-stack engineer with eight years of professional experience, specializing in React and TypeScript-driven web applications. He has progressed through roles from freelance and early engineering positions to technical consultant, senior engineer and now leading teams at VML Enterprise Solutions, while simultaneously contributing to engineering efforts at SECODE. Sebastian excels at solving complex front-end challenges—SSR, GraphQL, PWAs, performance optimization and TypeScript migrations—and brings hands-on experience with testing, animation and mobile cross-platform work. Colleagues value him for turning legacy codebases into robust, modern apps and for blending UI/UX sensibility with pragmatic engineering. Based in Skawina, Poland, he combines a decade-long coding habit with a problem-solver’s mindset and a track record of shipping customer-facing features under Scrum. An interesting detail: he often pairs motion-driven interfaces (framer-motion) with SEO and accessibility considerations to deliver both engaging and discoverable products.
