Rockstar🎓
Top SchoolElizaveta Shashkova is a Senior Software Engineer with over a decade of experience building developer tools, IDE features, and large-scale backend systems, currently working at JetBrains in Amsterdam. She has driven high-impact work on PyCharm and DataSpell—most notably a 20× Python debugger performance optimization and early Jupyter debugging support—and now focuses on AI-powered developer tooling such as RAG systems with embeddings-based search and incremental indexing for large codebases. A technical lead and mentor, she blends product-minded architecture with hands-on backend engineering to optimize performance, scalability, and developer experience. Her open-source contributions span debugger internals used by major tools (PyDev.Debugger) and test infrastructure improvements for pytest, reflecting deep expertise in debugging and testability that few tooling engineers combine.
