Description

Senior PHP/Symfony developer with over 10 years of experience in designing and operating critical, high-traffic backend platforms.

I primarily work on:

• Robust REST APIs with Symfony & API Platform

• Maintainable and scalable backend architectures

• Performance optimization (TTFB, application cache, Redis, reverse proxy, CDN)

• Advanced security (JWT, RBAC, complex business rules)

• Asynchronous processing (Symfony Messenger, RabbitMQ)

• Heavy technical migrations (Symfony, MySQL → PostgreSQL)

• Demanding production environments (CI/CD, Docker, monitoring)

I have worked on contexts with strong reliability and load constraints such as:

✔️ Critical B2B platforms

✔️ Media APIs with very high audience (real-time traffic peaks)

✔️ SaaS products exposed on web & mobile

Accustomed to Agile environments, I place a strong emphasis on:

→ Code quality

→ Long-term performance

→ Production stability

→ Product & business collaboration

Main Stack:

Symfony 5/6/7 · PHP 8.x · API Platform · PostgreSQL · Redis · RabbitMQ · Docker · CI/CD · React.js

🎯 Goal: build solid, high-performance backends ready to scale.
