Back to original languageAbout Jonathan
I design and develop web products and AI systems, from conception to deployment.
8 years of experience in fullstack development (Symfony, PHP, React Native), enhanced by sharp expertise in integrating AI agents and automating workflows. I have collaborated with major groups (UNIMEDIAS, EDF, OIE) and managed projects from A to Z as a developer and product builder.
What I bring concretely:
- Robust, scalable, and maintainable Symfony/PHP web applications
- Integration and orchestration of AI agents (Claude API, LLM pipelines, multi-agents)
- Cross-platform mobile applications in React Native (iOS + Android)
- Business dashboards, automations, and custom internal tools
- Product vision: I understand your challenges before writing the first line of code
A rare profile combining solid backend technical skills, product sensibility, and mastery of the latest generation AI tools.
Full remote. Responsive, rigorous, results-oriented.
