Summary
👤
Senior🎓
Top SchoolSebastian Leukhin is a Staff Software Engineer based in Berlin with around a decade of commercial experience building high-performance JavaScript and TypeScript web applications. He specializes in complex front-end systems, having driven design systems, micro-frontend migrations, and performance optimizations that measurably improved time-to-market and revenue. Comfortable switching between platform and product teams, he pairs hands-on engineering (React, Node.js, Next.js, Canvas) with pragmatic architecture and developer experience improvements like automated locale deployment and e2e test tooling. Sebastian is data-driven—using A/B testing to validate decisions—and contributes to open source while occasionally publishing technical articles. He has repeatedly scaled UI-kits and analytics across hundreds of developers, demonstrating an ability to turn internal tooling into company-wide leverage. An often-overlooked strength is his focus on DX: build-process, mock systems, and AI-assisted commands to make teams faster and codebases healthier.
