Romain Mouillard

Just like in improvisation, great engineering is about collaboration, adaptability, and making the best out of any situation. Listening, building together, and embracing failure as a step toward success are at the core of how I approach both leadership and technology.

I thrive on helping teams grow, communicate better, and deliver more efficiently, structuring processes and workflows to create an environment where people and products can scale. With a strong full-stack architecture background in PHP and TypeScript, I design scalable, maintainable, and high-performing solutions while ensuring high-quality delivery.

I also believe in sustainable choices, in tech and beyond, favoring efficiency, simplicity, and conscious production over excess. To me, engineering isn’t just about code, it’s about people, impact, and the systems we build to make things better.

Hard Skills

Over 15 years of experience with PHP, both in ESNs and client-side roles. Deep expertise in Symfony, from early versions to the latest, with the ability to tailor the framework to complex business needs.
