Back to original languageAbout Jonathan
External CTO and software engineer, I support the design and structuring of SaaS products, from technical architecture to production deployment.
I work on high-stakes topics:
- architectural choices and technical structuring
- setting up web platforms (SPA, SSR, API)
- improving performance and maintainability
- supporting and structuring technical teams
My approach is pragmatic and product-oriented: making the right technical decisions to build robust, scalable solutions adapted to real-world constraints.
In parallel, I design and develop SaaS solutions as CTO, which allows me to bring a concrete vision of product and technical challenges.
Experience with major clients and demanding environments (La Poste Groupe, Carrefour, Dassault Systèmes, Infopro Digital, Edenred).
