About Jason

JS Fullstack Developer (React / Node.js) | R&D & IoT Specialist

Passionate about technical innovation, I help companies create high-performance web applications and integrate complex software solutions. My R&D background allows me to combine the flexibility of the Web with the rigor of industrial systems.

Specializing in the JavaScript/TypeScript ecosystem, I work across the entire stack:

- Front-end: Creating responsive and intuitive interfaces with React.js.
- Back-end: Developing robust and scalable APIs under Node.js.
- R&D Specificity: Additional expertise in low-level development (C++) and software/hardware integration (concrete experience in 3D printing).

Having worked in demanding environments, I have developed a "problem-solving" oriented approach. I don't just code a feature: I ensure the longevity of the architecture, the quality of the code, and its long-term maintenance.

Whether you are a startup in the prototyping phase or an SME looking to modernize its digital tools, I am ready to take on your technical challenges.

📍 Based in Bailleul, I work mainly remotely but remain open to in-person meetings in the Lille region. Let's discuss your project!
