Top SchoolIlya Kuznetsov is a seasoned C/C++ software developer with over 15 years of hands-on experience across full-text search engines, mobile apps and video games, currently focused at Manticore Software. He has a deep background in search engine internals from long-term work on the open-source Sphinx project—implementing storage engines, a cost-based query optimizer, ranker plugins and on-disk compression—and continues to contribute bug fixes and feature improvements on GitHub. Ilya combines low-level systems expertise (storage, indexing, CRC/RT insert fixes) with pragmatic product delivery, having led small teams and shipped commercial games and mobile tools. He also has academic experience as a lecturer and holds a Master’s in Computer Science and Applied Mathematics, bringing a methodical, research-minded approach to engineering. Based in Voronezh, he’s known for refactoring tricky legacy code into maintainable components and for adding non-obvious improvements like reworking re-ranking logic into field filters that improve query behavior.
