About Lucas

Développeur Backend Senior & DevOps | Expert Python, Kubernetes, Architecture scalable

Avec plus de 10 ans d'expérience, je transforme des infrastructures complexes en solutions robustes et évolutives. Spécialiste des environnements à haute disponibilité, j'optimise les performances où d'autres voient des limitations.
Je résous les défis techniques que vous repoussez depuis trop longtemps:

APIs Python (Django/FastAPI) traitant des millions de requêtes quotidiennes
Migrations vers Kubernetes avec des déploiements automatisés via GitLab CI
Optimisation de bases de données PostgreSQL/MongoDB pour des performances accrues
Transition stratégique entre architectures microservices et monolithiques

Je ne suis pas simplement un développeur qui écrit du code – je suis un ingénieur qui comprend les enjeux business de vos décisions techniques. Mon approche pragmatique vise des résultats mesurables et durables.

Disponibilité immédiate pour:
✓ Renforcer votre équipe sur des projets critiques
✓ Optimiser vos infrastructures existantes
✓ Mettre en place des pipelines CI/CD efficaces
✓ Réaliser des audits techniques et recommandations d'architecture

Contactez-moi pour discuter de la manière dont mes compétences peuvent répondre à vos besoins techniques actuels.
