Summary
🤩
Rockstar🎓
Top SchoolViacheslav Kroilov is a senior software engineer with 12 years’ experience building high-performance systems and leading C++ framework and object-store teams at Pure Storage (Everpure) from Prague. He combines low-level expertise (CUDA, C++17, async primitives, memory allocation) with high-level orchestration across Java, Python, and distributed transactions, often debugging end-to-end stacks. A longtime contributor to the EPIJudge project (2.2k stars), he’s comfortable touching hundreds of algorithmic problems and managing merge-sensitive test frameworks. He champions asynchronous and concurrent programming and has shifted from language-centric tinkering to engineering robust system-level abstractions and developer ergonomics. Past roles span ML infrastructure, production NVVL improvements for accelerated video training, and photorealistic renderer development, reflecting a breadth across ML, graphics, and storage. Pragmatic and detail-oriented, he aims to make complex systems safer and easier for engineers to use.
