I am a freelance backend-focused developer with a strong emphasis on serverless AWS architectures and Node.js. I integrate fully into product teams, delivering reliable, high-performance, and secure solutions for demanding environments. I have worked on production systems for major accounts and public institutions (SNCF Connect, Ministère de la Justice) under real constraints such as load, security, CI/CD, incidents, and technical debt. On a day-to-day basis, I handle backend and API development (Node.js, AWS), serverless architectures (Lambda, API Gateway, DynamoDB, SQS, etc.), Infrastructure as Code and CI/CD pipelines (AWS CDK, Pulumi, Terraform, GitLab CI), refactoring and optimization of existing systems, and close collaboration with product, QA, and infra teams. I am available for backend/cloud team augmentation, API development/maintenance, and stabilization/improvement of platforms.…I am a freelance backend-focused developer with a strong emphasis on serverless AWS architectures and Node.js.
