I build developer tools for a living and tinker with them for fun. Currently a Principal Developer at Mendix, working on Studio Pro and Maia — the AI-assisted development experience for low-code. Before Mendix, I spent seven years at JetBrains shipping features for ReSharper and Rider, then led the ReSharper AI team. I also teach — courses on IDE development, programming languages, and machine learning at universities in Russia and Germany.
