Summary
👤
Senior🎓
Top SchoolMehdi Nasiri is a JavaScript-focused software engineer based in Berlin with nine years of experience building high-performance React and Next.js applications and commercial design systems. He has deep hands-on expertise with Nx monorepos, TypeScript, and architecting type-safe BFFs using tRPC and Fastify, having driven cross-team standards and reusable packages at scale. Mehdi combines front-end performance work (Core Web Vitals, custom OpenTelemetry middleware, advanced caching) with product impact—running frequent A/B/C experiments that boosted conversions and reduced latency. He’s led large migrations to modern stacks, recruited and mentored frontend teams, and shipped reusable UI libraries (including an npm date-picker supporting Gregorian and Jalali calendars). Always curious about backend systems, he’s actively expanding into full-stack responsibilities while keeping a pragmatic, metrics-driven approach to developer experience and delivery.
