About Sven

I am an experienced JavaScript and TypeScript full-stack developer, trained at Ecole 42 and passionate about programming.

I have contributed to numerous projects of varying sizes, often technically and visually demanding. All these challenges I have had to overcome have given me a taste for continuous learning and perfecting my skills in software development.

My most significant achievement to date is having created with a partner a SAAS web and mobile application for incident management in the hotel industry. This experience has enriched me greatly both technically and in project management. Having had to manage all components of the application, from design to database management, I was able to get an overview of the requirements of a modern application.

I am currently undertaking freelance web and mobile missions for my clients. I am comfortable with the TypeScript ecosystem and my preferred technologies are React.js/Next.js, Tailwind CSS for styling, and Prisma for database management. However, I am flexible and can adapt to your technical stack requirements.

📧 Feel free to contact me to discuss how I can contribute to the realization of your project!

I worked with Sven, him as a front-end developer and me as a back-end developer, so the review I am giving here is a technical one. We had several overlapping complexities: product definition, somewhat specific design, back-and-forth on functionalities. Sven was able to propose solutions while being rigorous in terms of technique, specifications, and incorporating revisions. - Technically, Sven's code is easily modifiable if we wish to make future changes. - Regarding specifications, Sven took into account many cases we hadn't initially thought of, which brings appreciable robustness to the final result. - Finally, during the acceptance testing phase, Sven was extremely responsive, taking into account all our requests. Furthermore, the speed of evolution according to the requests demonstrates the quality of his code. I highly recommend him. He is also very pleasant on a human level.
