About Jérémy

Has your app outgrown its architecture and performance is declining? This is exactly the kind of issue I address. 👇

In a few points 📈
• 12 years on the same platform in a startup: design, refactoring, scaling, and infrastructure, still in production today
• Complete refactoring of a complex real-time application (WebRTC) without service interruption
• Technical lead of a team of 10 people: recruitment, training, implementation of best practices
• Taken over existing codebases from other clients: diagnosis, performance issue resolution, frontend and backend restoration

How I work 💻
My role doesn't stop at implementation: I challenge technical and product choices by considering your business objectives, and I flag risks before they become blockers.

"The type of collaborator every CTO wants on their team" - Justin Briard, CTO @ Datalok

Up-to-date tools and practices (recent frameworks, AI) to accelerate delivery without sacrificing quality.

Do you have a technical issue blocking your app, technical debt, or a new requirement?
Tell me in one sentence what's holding you back, and I'll respond with an initial approach.
