- 🚀 I'm a member of the Rust Leadership Council and the compiler and infrastructure teams. I spend a lot of time contributing to (usually Rust) open-source projects.
- ⚡ I did my PhD in High-performance computing at the IT4Innovations supercomputing center.
- ⭐ I enjoy programming in Rust
, Python 🐍, Kotlin, and TypeScript. Sometimes I also use C, C++, Java, Javascript or PHP.
- 🏃♂️ I have participated in ACM SIGMOD programming contests (🥈2019, 🥈2018, 2017, 2016).
- 🤝 I love contributing to various open source projects, such as the Rust toolchain, Rust compiler benchmark suite or IntelliJ Rust plugin.
I am a proud member of the following Rust teams and working groups:
- Leadership Council: making sure that Rust succeeds
- #t-infra: maintaining CI and various other Rust infrastructure in the Infra team
- #t-compiler: improving the Rust compiler and associated tooling
- #wg-compiler-performance: improving the performance of the Rust compiler
- #t-bootstrap: maintaining the Rust compiler bootstrap system
- #t-triagebot: maintaining the Rust triage and review bot
- #wg-parallel-rustc: parallelizing the Rust compiler
- #t-docker: helping maintain the Rust Docker images
- #t-bors: developing the bors merge bot
- #t-survey (co-lead): performing surveys to gain insight into the Rust ecosystem
- #t-mentorship (co-lead): leading mentorship programs, such as GSoC
- #wg-rustc-dev-guide: improving the Rust Compiler Development Guide
