Researching storage systems with extreme performance.
See DIS/LSVD, BUSE or BS3.
Teaching Operating Systems at EPFL as a Head TA.
Computer Science PhD student at EPFL.
Advised by Prof. Sanidhya Kashyap and a member of RS3Lab.
Trying to improve Czech academia by writing why and how do PhD abroad.

Was a lecturer at Charles University (Dept. of Distributed and Dependable Systems).
Had a business on building customized servers and open-source software deployment.
I replaced dozens of commercial hypervisors and storage solutions with open-source.
Was a systems engineer (storage and networking). Also interned at Red Hat twice.
Converted to systems research from AI/ML.
Was extremely lucky to work with professors
- Peter Desnoyers from Northeastern University,
- Petr Tuma from Charles University and
- Ondrej Kuzelka from Czech Technical University in Prague.
Obtained degrees with miscellaneous honors from
- Charles University (MS in Systems),
- Czech Technical University in Prague (MS in AI/ML) and
- Brno University of Technology (BS in general CS).

Operating Systems, Storage, Networking and Computer Architecture.
With a particular focus on high-performance I/O.
Artificial Intelligence and Machine Learning in the previous life.
