Rockstar🎓
Top SchoolAlexey Stepanov is a Senior System Software Engineer based in the Randstad with a decade of experience building and hardening backend and system-level Python software. He has driven production improvements at NVIDIA and Bright Computing and modernized widely used open-source projects like ipykernel and aiohttp by removing legacy cruft, adding type hints, and improving error handling and test coverage. Pragmatic and iterative by nature—self-described as a “lazy developer”—he prefers incremental optimizations that reduce long-term toil, such as migrating code to asyncio, introducing linters/formatters, and cleaning Python2 artifacts. His background spans QA, test-engine design, and cluster management, giving him a rare mix of deep systems understanding and practical developer ergonomics.
