Full Stack Developer @ Echosens

About

I'm a passionate full‑stack JavaScript engineer from Paris with 10 years of experience. I'm an independent developer with over 7 years of experience as a micro‑entrepreneur and a SASU, now I help startups and SMEs to create efficient web apps with React and Node JS. My core strengths: - Client‑focused execution: deploying customer‑centric large‑scale application with demonstrable results. - Technical: modern front‑end (React, Next, Redux/Context, Tailwind, Material UI, CSS 3), back‑end APIs (Node JS, Express, Nest JS, PostgreSQL, GraphQL), and DevOps fundamentals (CI/CD, Docker, AWS). - Problem solver: optimizing performance, improving UX, securing APIs, and making complex features easy to maintain using advanced design patterns. I have successfully done projects such a web platform which has improved customer engagement by 30% in 8 weeks, a complete rewrite of a huge legacy app within 2 weeks, an MVP SaaS (software as a service) enabling users to easily track and manage tasks through devices and more. When I am not coding, I continue studying new tech trends and team management. Let’s work together! If you’re in need of a freelance full‑stack developer who can provide quality web and mobile solutions, don’t hesitate to contact me.
