- FreelanceSenior Fullstack DeveloperSOFTWARE PUBLISHINGSeptember 2025 - Today (9 months)Toulouse, FranceLong-term contract mission with a North American B2B e-commerce platform, in a context of strong growth and technical debt to resolve.What I bring daily:
- Making maintainable what was no longer so. Taking over critical modules that had become unmanageable (order flow, planning) to transform them into clear, testable architectures that are easy for the rest of the team to evolve.
- Scaling what's holding back. Systematic audit and resolution of bottlenecks (heavy queries, critical endpoints, cache) with a progressive and secure approach.
- Equipping the team to go faster. Implementation of a unified monorepo, an internal design system, readable monitoring. The goal: for a junior developer starting tomorrow to be productive within a week.
- Maintaining a strong requirement for quality without blocking delivery. Strict typing, tests, framework conventions. Not out of dogma, but because it's what allows a product to last.
