Description

Backend engineer with 15+ years of experience, specialized in PHP / Symfony and distributed systems.

👉 At Sparteo, I led the Analytics API platform across multiple ad-tech products (Viously, Actirise, FastCMP), driving architectural decisions, scaling analytics systems and managing a small engineering team.

👉 Previously, I contributed to the backend architecture of the Bedrock streaming platform (M6 Group), working on high-traffic microservices handling subscriptions, payments and multi-tenant systems.

I focus on building reliable, scalable and maintainable systems, with a strong emphasis on performance, data processing and developer experience.

Open to backend / lead roles (permanent or freelance), on-site or remote (Madrid, Lyon, Paris).
