Build it. Ship it. Keep it up.

I build and run cloud platforms — Kubernetes, Terraform, CI/CD — and the applications on top, from event-driven / DDD back-ends to Next.js and Vue front-ends. The goal: fewer incidents, faster releases, calmer on-call.

§ testimonials

What people say

Alexandre is a highly valuable team member. He has a remarkable ability to adapt and has quickly gained expertise in highly technical subjects by leveraging his experiences. Well-versed in coding best practices and design patterns, he has a strong understanding of Object-Oriented Programming (OOP) and frameworks such as Laravel for PHP and FastAPI for Python, and React for front-end applications. This has enabled him to frequently propose solutions for complex technical challenges. In addition to his professional qualities, he has excellent interpersonal skills and can easily collaborate with colleagues in a team environment.

— Thomas G.

I had the opportunity to work with Alexandre during a fairly long assignment on both back-end and front-end development, and we immediately got along! Alexandre was just as, if not more, invested than my internal colleagues, with a true passion for development that led him to dedicate personal time to improving his skills every day. Self-reflection is a trait we should all maintain to move forward with humility in our professional lives, and I therefore wholeheartedly recommend him—not only for his technical skills but also for his human qualities!

— Mickaël R.

I had the pleasure of collaborating with Alexandre, who consistently impressed me with his ability to learn, form opinions on technological practices, and his unwavering curiosity. Reliable and dedicated, I would be delighted to work with him again!

— Thibault M.
