  4. 2023–2024

    Memoriboost

    Founded and launched an AI-assisted flashcard product with spaced repetition. I later ended it to focus on salaried work, open-source work, and my family. The experience strengthened my product vision: balancing technical interest, business value, maintainability, technical debt, and ease of evolution.

    Junior developer roles at Maeva and Cocolabs. At Maeva, I contributed to internal administration tools for a high-traffic platform. At Cocolabs, I worked on frontend and backend tickets for a SUEZ marketplace.

  7. 2018–2021

    Learning & Freelance

    Focused on programming, object-oriented design, networking, Linux, hardware, and other computer science fundamentals. Alongside this, I worked for several clients on websites, frontend development for a medical application, and a language-learning product. I also made small contributions to the PHP open-source ecosystem.

Current studies

What I’m learning now

Mathematics

I began studying mathematics out of curiosity and to better understand scientific papers that rely on statistics. I unexpectedly fell in love with the subject, especially pure mathematics. In 2026, I enrolled part-time in a BSc in Mathematics, where I expect to combine pure and applied mathematics.

Systems & infrastructure

As AI tools automate more implementation work, I’m focusing on the engineering decisions where deeper judgment still matters. I’m studying system design, cloud infrastructure, DevOps, and orchestration to better understand how reliable systems are designed, deployed, and operated.

Thomas Cadorel

Jean is an outstanding developer.

We've been collaborating on different kind of projects : a complex loyalty management system, a Telegram app, and a blockchain bridge system. Whatever the project is, he's handling it without any problem. It was a true pleasure working with him cause you always know the delivery is gonna be almost perfect. He does what he says and says what he's doing (and even more), which is, as a project manager, exactly what I expect from my team.

He has a comprehensive product and even a business vision, so he always finds technical solutions that match product requirements while challenging exactly what needs to be challenged.

As a project manager, working with him is a true pleasure. He consistently delivers high-quality code, anticipates potential issues, simplifies complex concepts, communicates, and, most importantly, he is a genuinely kind and good person. I'm looking forward working with him again !

I had the pleasure of working with Jean and would highly recommend him as both an excellent engineer and a great teammate.

As a frontend developer, what I appreciated most was how easy Jean made collaboration between frontend and backend. He has a real ability to understand product needs, explain technical decisions clearly, and work with the team to find practical solutions. His openness and communication helped us move faster and avoid unnecessary complexity.

Jean approaches challenges with a thoughtful and pragmatic mindset. He’s always willing to share his knowledge, listen to different perspectives, and support the people around him. Whether discussing APIs, architecture, or implementation details, he creates an environment where collaboration feels natural and productive.

Beyond his technical expertise, Jean is someone you can genuinely rely on. He’s approachable, professional, and brings a positive attitude to every project. I would gladly work with him again.

Technically sharp, kind, and exactly the kind of mentor you hope to find early in your career.

Full testimonial

Tristan Azalot

I worked with Jean during my internship at Avicenne Studio, collaborating on a Qubic-Solana bridge where he introduced me to Fastify and shared his Node.js expertise in a genuinely hands-on way.

What stood out most was his pedagogy.
He always took the time to explain the reasoning behind his decisions, making complex concepts easy to grasp.
He genuinely cared about understanding, not just execution, and was always open to questions, attentive to feedback, and focused on making sure things actually clicked rather than simply got done.

Technically sharp, kind, and exactly the kind of mentor you hope to find early in your career.
