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 write open source code on github.
Finally, I’m a competitive programmer and ICPC SWERC gold medalist.
