Summary
👤
Senior🎓
Top SchoolValentin Grigorev is a software developer and researcher with a decade of experience, focused on performance tooling and low-level systems engineering. Since 2020 he has been building cross-platform .NET profilers and tracing infrastructure at JetBrains, including EventPipe integrations, timeline profiling, allocation sampling, and lightweight coverage for continuous testing. Earlier he co-designed PosDB, a distributed disk-based columnar DBMS, owning query processing, parallelism strategies and disk-optimized aggregation—work that produced multiple research papers and his theses. Comfortable in C++ as his primary language, he also frequently uses C# and Kotlin and bridges runtime internals with higher-level tooling via P/Invoke and cross-platform libraries. Based in Munich, he combines academic rigor with production-grade engineering, and has a particular knack for making deep runtime features work reliably across Windows, macOS and Linux.
