Experienced fullstack developer with over 10 years of experience, I design and develop custom applications based on your needs. Whether it's creating a POC, optimizing existing infrastructure, or strengthening a technical team, I fully commit to realizing your projects. My experience atShine(neobank acquired by Société Générale, from 0 to 100,000 customers in 3 years), where I was the seventh employee, allowed me to evolve from the role of fullstack developer to tech lead, engineering manager, and staff engineer, within a team of 40 developers. I thus contributed to the company's growth while developing in-depth knowledge of the specific needs of early-stage startups, as well as those of more mature companies.

I have strong experience in theJavaScript/TypeScriptecosystem, andNode.jsfor backend architecture, whether in microservices or monoliths. My skills include API design (public or private), managing authentication and permissions, implementing event-driven systems, as well as usingSQLand object-oriented databases. On the frontend, I have solid expertise inReactand **React Native**, having developed several applications with these technologies.

If you are looking for a developer capable of adapting to your needs and working hand-in-hand with your team, do not hesitate to contact me to discuss your projects. I look forward to hearing from you.
