Description

🚀 Senior Backend Developer with over 8 years of experience, I help companies (Scale-ups, Large Enterprises, E-commerce) design, refactor, and scale their APIs and distributed architectures.

My goal? To combine delivery speed with code robustness. I use AI tools (Claude, ChatGPT, Copilot...) daily to accelerate standard code production and focus on what adds the most value: architecture, security, and business performance.

🛠 MY TECHNICAL EXPERTISE:

• Backend: Node.js, NestJS, TypeScript, PHP (Slim Framework).

• Architecture: Microservices, REST / BFF API, Clean Architecture, Serverless.

• Cloud & DevOps: AWS (Lambda, ECS, EC2, DynamoDB), GCP, Docker, CI/CD.

• Databases: Oracle, MongoDB, SQL / NoSQL.

• Quality: TDD, Jest, Mocha, SonarQube.

• Frontend (Bonus): React.js, Angular.

💡 WHY WORK WITH ME?

✔️ Autonomy & Reliability: Accustomed to Full Remote and demanding environments (FranceTV, Sephora, Swiss Life).

✔️ Code Quality: I am uncompromising on tests (unit/integration) and maintainability.

✔️ "Problem Solver" Mindset: Whether migrating a monolith, managing complex version upgrades, or handling load spikes, I am solution-oriented.

Ready to scale your projects? Let's discuss!
