Yassine Hamouten, senior backend engineer & tech lead
As a freelance Tech Lead, I help product teams design, modernise and evolve reliable backends. I shape technical decisions while staying hands-on in the code. At Decathlon, I helped optimise an API as its monthly traffic grew from 7M to 55M, sharply reducing response times and eliminating errors.
About me
Backend, APIs & distributed systems
More than 10 years in backend engineering, primarily with PHP/Symfony: API design, event-driven systems with Kafka and RabbitMQ, and high-volume services. I also work on reliability, performance and the gradual modernisation of existing applications.
Tech lead & entrepreneur
I support engineering teams, set technical standards and mentor developers. Alongside freelance work, I build and run Role.so, a SaaS that turns recruiter outreach into branded recruitment pages and shows how candidates respond.
