WHAT I DO

01

API Design & Dev

Robust REST and gRPC APIs built with .NET and documented with OpenAPI. I focus on contract clarity, versioning, and performance that holds up under real traffic.

Database Engineering

Schema design, query optimisation, and migration strategies that keep your data reliable. From relational models to caching layers that cut latency.

Infrastructure & DevOps

Containerised, observable, and easy to deploy. I set up CI/CD pipelines, Docker environments, and cloud infrastructure so releases stop being scary.

ABOUT

Ibuildthebackendsystemsthatmakegreatproductsworkreliable,scalable,andreadyforproduction.

I'm Matheo, a backend software engineer based in France. I'm currently studying at Epitech while working at Betclic, where I own payment microservices end-to-end in a domain-driven team.

My focus is backend engineering: designing APIs, building and maintaining microservices, setting up CI/CD pipelines, and keeping systems observable and secure in production. I care about code that's correct, resilient, and easy to reason about under pressure.

When I'm not building systems, I'm exploring distributed architectures or going deeper into whatever makes backend engineering more robust and maintainable.
