Top SchoolAmin Jafari is a Senior Frontend Developer based in Berlin with over a decade of hands-on experience shaping performant, scalable web and mobile applications. He has driven multiple legacy-to-Next.js/TypeScript migrations, authored custom UI libraries and design systems, and boosted performance metrics (e.g., a +40% improvement at Moonfare) while raising test coverage to production-safe levels. Comfortable across React, Next.js, React Native, vanilla JavaScript, CSS and GraphQL, he combines deep technical craft with team leadership—building guilds, mentoring engineers, and delivering company-wide tech talks. Amin has a proven track record of shipping high-security mobile authenticators, custom charting tools using D3, and ultra-lean frontends under strict bundle-size constraints.

Fluent in transitioning organizations to modern frontend stacks, he thrives on turning legacy complexity into maintainable, high-quality products.
