Summary
👤
Senior🎓
Top SchoolAlexey Kalina is a Senior Machine Learning Engineer with 10 years of experience building production ML features for developer tools, currently advancing AI-powered search and ranking at JetBrains in Munich. He led the development and rollout of ML-powered code completion ranking and a Full Line Code Completion feature—now default in many JetBrains IDEs—improving completion selection rates and increasing one-line completion coverage from 20% to 50% across languages. Alexey combines hands-on software engineering with rigorous evaluation practice, having designed offline/online evaluation frameworks, A/B testing pipelines, and continuous quality diagnostics that sped feedback loops and made model improvements repeatable. He has a strong foundation in software and applied math from Saint Petersburg State University and a background spanning full-stack and .NET development, which gives him practical product sensibility beyond ML. Notably, he built end-to-end workflows that enabled rapid language support expansion and introduced offline evaluation tooling from scratch—work that quietly scaled IDE intelligence across JetBrains’ product line.
