Senior Full-Stack Engineer specializing in React, Next.js, and TypeScript — with a track record of shipping production SaaS applications that are fast, maintainable, and built to scale. Over the last 5+ years I've led frontend architecture and full-stack delivery for SaaS startups across Europe, working closely with founders, product teams, and engineering leads to turn complex requirements into clean, performant products. 🎯 WHAT I'VE DELIVERED ✅ Led the full architectural rebuild of a credit management SaaS platform — reduced the codebase from 150,000 to 40,000 lines (73% reduction) while cutting initial load time from 4 seconds to 1 second. ✅ Built a dual-platform web + Electron application with 85% shared codebase, deployed to research centers including Tecnalia, with real-time WebSocket data flowing from hardware sensors to the UI. ✅ Drove a 20% increase in conversion on a career-tech SaaS that grew to 50,000+ users and helped close €1M in funding across two rounds. 🛠 WHAT I BRING TO YOUR PROJECT ✔ Deep expertise in React, Next.js, TypeScript, and Tailwind CSS for modern, performant frontends ✔ Full-stack capability with Node.js / Express and any TypeScript backend framework ✔ Production experience with AWS, Vercel, Docker, PostgreSQL/MySQL, and CI/CD pipelines ✔ Strong focus on performance optimization — code splitting, eliminating request waterfalls, bundle size, Core Web Vitals ✔ Experience leading small engineering teams and establishing frontend standards 👤 I'M A GOOD FIT IF YOU'RE ▸ A SaaS founder or CTO who needs a senior engineer to own frontend architecture ▸ A team with a slow, bloated, or hard-to-maintain frontend that needs rescuing ▸ Building a data-heavy dashboard, internal tool, or B2B product where UX and performance actually matter ▸ Looking for someone who can move between frontend and full-stack as the project demands I work best with teams that value clean code, clear communication, and shipping things that actually work in production. 📩 If that sounds like your project, send me a message — I'd love to hear what you're building.
