Marc-Antoine Dutoit

Madsaas supports companies and startups in the design, redesign, and scalability of modern SaaS solutions.

I define robust and scalable web architectures, ensuring technical consistency and software quality throughout the product lifecycle.

I primarily work with Node.js / NestJS / React / TypeScript, using PostgreSQL for relational data and MongoDB for logs and analytics.

I implement microservices, serverless architectures, and cloud deployments (AWS, Azure), within an agile, collaborative, and fully remote environment.

As a Developer and then Lead Developer at Hospit’Access, I supervised the development of a SaaS platform designed to streamline patient admissions between doctors and hospitals.

I was responsible for the technical structuring of the project (NestJS, React, TypeScript), contributed to the implementation of a certified HDS cloud infrastructure, integrated a reliable CI/CD, and ensured GDPR compliance, in line with the sensitive issues of the healthcare sector.

Worked in a small team, with strong involvement in design, code supervision, and developer support on quality, security, and best practices.

Assisted Syswings, a B2B hosting provider and ISP, in modernizing its software infrastructure and automating its critical services. My role evolved from classic Full Stack management to a strong specialization in CI/CD and integration of Open Source services.
