Description

Over the last 15 years working with startups and scale-ups, I have designed and evolved backend systems end-to-end: from API design to distributed architectures and cloud infrastructure.

I have worked on high-throughput data platforms, reliability engineering projects, and complete migrations to modern containerized environments.

What I bring:

→ Microservices & API design (OpenAPI, GraphQL)

→ End-to-end product feature development with a strong product culture

→ Test-driven development (TDD)

→ Infrastructure as Code (Terraform, AWS) & DevOps practices

→ CI/CD (Travis, Jenkins, GitHub Actions)

→ Containers & orchestration (Docker, Kubernetes, ECS/EKS)

→ Observability, performance & reliability (SRE practices)

→ Agile methodologies (Scrum, Kanban, Shape Up)

→ Mentoring and knowledge sharing

→ AI-assisted development

Tech Stack: Ruby / Rails, Elixir, .NET, Python, PHP, PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, AWS, Terraform, Docker, Kubernetes.

🌍 Based in Paris, available in full remote worldwide or hybrid in Paris

🗣 English, French, Italian, Thai (beginner)

Preferred areas:

→ System scaling

→ Performance & reliability

→ Architecture design

→ Improving and modernizing legacy codebases

→ Helping teams deliver smarter and faster

I am passionate about the web in all its forms: from ambitious distributed platforms to more modest projects that simply need the right foundation to grow. No project is too big or too small if it's interesting.
