Software Engineer

About

I enjoy building complex systems that have a real impact on people's lives, and that display elegance and simplicity of software design.

What drew me to engineering wasn't the code, it was the architecture. Understanding how pieces interconnect, how data flows, where bottlenecks hide. Now, I use my skills to build systems that are scalable, maintainable, and secure.

At Meetway, I learned that technical decisions are business decisions. At iExec, that blockchain infrastructure demands different mental models. At CGI, that enterprise scale reveals problems startups never encounter.

Now I approach every system the same way: understand the constraints, question the assumptions, build for what matters and what provides value.

On my free time, I'm currently growing an interest for Blockchain systems, creating the future of PQC security for Ethereum ecosystem, with a deep learning of Cairo, as well as Golang and Rust to wire it all together.

Current Focus

  • Distributed event systems
  • Cloud-native architecture
  • zk-STARKs using Cairo
  • Golang development

Experience

Startups, consulting, enterprise. Each context taught different lessons.
