NLAbout Nathan
Bonjour, je suis Nathan Lebon, Software Engineer spécialisé en backend et infrastructures scalables.
Passionné par l’architecture logicielle et les systèmes distribués, j’ai développé des microservices robustes en Golang et Node.js, traitant des centaines de milliers de requêtes quotidiennes. Fort de mon expérience chez Leboncoin (Adevinta) et Nooco (Vinci), j’ai conçu des solutions performantes en exploitant Docker, Kubernetes, AWS et Kafka.
🔹 Ce que j’apporte :
✔️ Développement backend optimisé (Go, C, Node.js)
✔️ Architecture microservices & gestion d’événements (Kafka, RabbitMQ)
✔️ Sécurisation des applications (authentification, OAuth2, 2FA)
✔️ Optimisation de la scalabilité et des coûts cloud
✔️ Monitoring et observabilité (Datadog, Kibana)
✔️ Approche Test-Driven Development et CI/CD efficace
🚀 Mes objectifs : J’aime travailler sur des projets exigeants en termes de performance, sécurité et scalabilité. Que ce soit pour optimiser des architectures existantes ou concevoir des solutions robustes from scratch, je suis prêt à relever de nouveaux défis !
