About me (resume)
I’m a musician, entrepreneur and programmer. I studied mathematics and computer science at École polytechnique and ETH Zurich.
My main occupation is studying music and orchestral conducting. I also regularly give piano concerts.
Apart from music, my main areas of expertise are computer science and financial economics. Currently, I’m the co-founder and CTO / tech lead of two projects:
- Secrecy.me provides people with a private and secure cloud experience
- Gematria Technologies bridges the gap between qualitative and quantitative insights in Finance using NLP.
On the little free time I have left, I do research (I am a PhD candidate in Financial Economics) and write open source code on github.
Previously, I was a competitive programmer who participated in ICPC, the most prestigious programming contest in the world.
My team became Southwestern Europe champion and gold medalist and achieved France’s all-time record at the ICPC World Finals.
