Introduction

About me

I'm a software engineer based in Lausanne, pursuing a Master's in Computer Science at EPFL after completing my Bachelor's there. At Qube Research & Technologies I worked as a Quantitative Analyst, building and optimizing pipelines that process large-scale financial datasets for quantitative research and trading strategies. Before that, I was a Back-End Engineer at Proton, refactoring core systems for modularity and expanding test coverage across the codebase.

My interests sit at the intersection of quantitative finance, low-latency systems, cybersecurity, and reverse engineering. I like understanding how things work under the hood — and building software that holds up at scale. Alongside my studies, I manage a live investment portfolio in the University of Zurich's Portfolio Management Program, and I'll be joining Citadel as a Software Engineer Intern in summer 2026.
