Fullstack TypeScript Architect & Dev | Refactoring legacy & building projects from scratch
Do you have a project to take over? A legacy where the team has left, an MVP put together hastily that needs industrializing? Or perhaps an application to build from scratch, properly, all the way to deployment?
This is exactly where I come in.
As a fullstack TypeScript developer and architect, I deliver code you don't have to rework: on my current mission (Airbus, critical systems), only one bug has been reported since the beginning and zero regressions on the features I've delivered. This isn't luck; it's a method: Domain-Driven Design, decoupling, explicit state machines, and automated testing (TDD).
How I intervene:
➤Takeover & RefactoringI take over a codebase burdened with technical debt and make it clean, tested, and extensible, without breaking the existing system. Refactoring tightly coupled areas under time constraints, without regressions.
➤End-to-End 0-to-1Design, development, deployment, DevOps, and environment configuration (AWS, CI/CD, Docker). A versatile architect, I take projects from concept to production.
➤Reliability & Performance at ScaleInfrastructure scaled to 50,000+ concurrent users (FeelingSports), latency reduced by 40%, deployment times reduced by 80%.
Regarding the tech stack, I prioritize business logic over frameworks: end-to-end TypeScript, and I work with SvelteKit (expert), Next.js, or Angular depending on your context. I also transfer best practices (Clean Code, testing strategies, architecture) to upskill your teams.
