About Soufian

Ingénieur logiciel senior avec plus de 9 ans d’expérience, spécialisé dans les systèmes à haute performance. Je possède une solide expertise en développement logiciel, avec un parcours éprouvé dans la conception, la création et le déploiement de solutions évolutives sur le cloud.
Au cours des deux dernières années, j’ai choisi de m’impliquer dans des missions en freelance afin de relever une variété de défis techniques, allant du streaming en temps réel à la modernisation d’API à grande échelle.
Mon objectif est de livrer des solutions propres, pragmatiques et bien architecturées répondant aux besoins métier les plus critiques.

J’assure la prise en charge complète du cycle de vie — de la conception jusqu’au déploiement et à l’optimisation dans le cloud — et je m’épanouis dans des environnements où le leadership technique et la contribution directe au code se rejoignent.

Technologies principales : PHP, Symfony, Python, Flask, FastAPI, Golang, Node.js, AWS, Docker, REST APIs, GraphQL, MySQL, PostgreSQL, CI/CD.

Ouvert aux opportunités en contrat en remote ou à temps plein, où je peux mettre à profit mes compétences en architecture et en résolution de problèmes sur des projets stimulants.
