Senior🎓
Top SchoolJulien Manganne is a Symfony-certified backend PHP developer with 11 years of experience building and leading teams to deliver robust REST APIs and progressive refactors for both agencies and product companies. Based in Paris, he has shipped API-first architectures at Yousign and Deezer, designed contract-first public APIs, and led a five-person backend team at Meero where he introduced strong craftsmanship practices (TDD, pair programming, refactoring). His technical toolkit spans PHP 7–8, Symfony 4–6, API Platform/FOSRest, RabbitMQ/SQS, Elasticsearch, Redis and PostgreSQL, with hands-on experience in CI/CD, Kubernetes and API contract workflows. Calm, curious and decision-oriented, he combines technical ownership with people coaching to sustain high-quality delivery. A longtime advocate of Agile values, he often pairs incremental migration strategies (double-write, message retry) with pragmatic testing and monitoring to reduce risk.
