Thomas Papin

20 years designing and delivering products, including 14 as a leader at JULOA

I have supported over 90 web & mobile applications, from MVP to production tools for large companies.

My specialty: I wear both the product and technical hats.

I understand a need, I propose a product that holds up functionally and ergonomically, and I can design and code it. Not a developer executing specs, not a manager who has put down the keyboard — both. This is precisely what allows for making the right technical decisions without disconnecting from the product side.

My playground

→ React Native / Expo — main expertise, from MVP to multi-country app

→ React / TypeScript / Next.js — modern, performant, maintainable front-end

→ Django / Node.js — backends designed to last

→ Architecture, DevOps, CI/CD — what prevents a project from collapsing after 2 years

What I do

🔹 Product design & build — I take an idea or a vague brief and deliver a functional product, from product trade-offs to production code.

🔹 Team reinforcement (lead / expert) — I join your React Native / React projects operationally, I deliver, and I train your teams along the way.

🔹 Refactoring & audit — I have taken over and straightened out codebases full of technical debt (e.g., Bataillog).

🔹 Part-time CTO — processes, recruitment, architecture, code reviews, mentoring.
