Building reliable software from the operating system to the cloud.

Currently: Systems Engineer Intern @ CodSpeed — performance instrumentation, Linux runtime tracing, benchmark runners.

Software Engineering student at 42 Paris, specializing in Systems Programming, Platform Engineering, and DevSecOps. I enjoy understanding how software works beneath the abstraction layers — from Assembly and Linux internals to distributed systems and cloud-native platforms.

Systems Performance: Enterprise and the Cloud (Brendan Gregg) · Operating Systems: Three Easy Pieces · The Rust Programming Language · A Philosophy of Software Design

Build software that is understandable, observable, reproducible and maintainable.

Great engineering isn't only about writing fast software — it's about building systems that are easy to deploy, monitor, debug and evolve.

Outside of software, I enjoy disciplines where progress comes through patience, consistency and continuous improvement. Next adventures: Snowboarding & Surfing.
