Sébastien Vérité

I design architectures before writing the first line of code, with a simple goal: to deliver reliable, maintainable, and durable systems.

PHP Symfony developer with 20 years of experience (including 14+ on Symfony), I have designed and evolved complex SaaS platforms, APIs, and applications in production.

From 2019 to 2026, I single-handedly developed a SaaS in production, in direct collaboration with the Product Owner. End-to-end responsibility: architecture, scalability, technical debt, deployment, and maintenance.

I place great importance on quality, while remaining pragmatic. Modern tools today allow me to iterate quickly without compromising robustness.
