About Jonathan

🎯 Your Symfony application is slowing down. The code has become difficult to evolve. Each new feature takes twice as long as before.

This is exactly where I come in.

I take over existing Symfony projects, refactor, optimize, evolve features, without breaking what works. No complete rewrite. No long ramp-up.

Just a senior dev who understands your code faster than you'd expect.

📈 What this looks like in concrete terms
→ -84% on the processing time of an import pipeline (batch processing + SQL tuning)
→ Asynchronous architecture with RabbitMQ to handle load peaks
→ Correction of security vulnerabilities identified during an audit, RBAC, secure upload, CI/CD

→ Real-time REST API with Symfony/API Platform and Mercure
