Senior Frontend / Full-Stack EngineerMohamed Ismail
TypeScript · React · Next.js · Node.js · GraphQL — 10+ years building for fintech, blockchain and SaaS
I build resilient, high-performance web applications and the platforms behind them — from customer portals at Nationale‑Nederlanden to blockchain tooling at Kadena. I care as much about developer experience as user experience.
AboutA decade of turning fragile frontends into resilient systems
I'm a Senior Frontend / Full-Stack Engineer based in the Netherlands, with 10+ years building scalable, high-performance web applications in TypeScript, React, Next.js, Node.js and GraphQL. Across my career I've repeatedly led migrations from JavaScript to TypeScript and REST to GraphQL, and broken monolithic frontends into modular, component-driven architectures — improving maintainability, developer velocity and system reliability.
I've designed GraphQL schemas, implemented micro-frontends with Webpack Module Federation, set up distributed tracing with OpenTelemetry, and built reusable deployment frameworks. Earlier in my career I delivered UI work for global brands including Porsche, LG, Air France and Citi Bank, and built blockchain tooling and documentation platforms at Kadena.
I work TDD-first, pair regularly, and have a consistent track record of mentoring engineers — including four-plus years at SurveyMonkey coaching junior developers. Clean architecture and fast feedback loops let both developer experience and user experience move faster, together.
