Description

Do you have a SaaS product to launch, a web or mobile application to evolve, or a technical team that needs a clear direction?

I act as a Tech Lead Full-Stack to frame, architect, and deliver robust web and mobile products, from the first version to their industrialization.

I support startups, SMEs, and product teams on subjects that concretely advance a project: architectural choices, development of key features, quality, performance, technical debt, APIs, deployment, and knowledge transfer to teams.

My main expertise: Node.js, TypeScript, NestJS, React, Angular, React Native, SaaS architecture, REST APIs, PostgreSQL, Docker, CI/CD, and cloud.

With over 8 years of experience in web and mobile development, I have worked on various products, both in creation, redesign, and evolution of existing platforms. I combine a product vision with engineering rigor: delivering quickly without creating technical debt that hinders future progress.

I can help you in particular to:

Launch or take over a web and/or mobile SaaS
Structure a sustainable TypeScript, Node.js, and NestJS architecture
Develop an API, a back-office, or a business application
Accelerate a blocked roadmap or make an existing system more reliable
Technically mentor a team and upskill developers
Audit a codebase, prioritize technical debt, and secure a production deployment

I work in French or English depending on the project context.

Let's talk about your product, your team, and your technical priorities.
