Summary
🤩
Rockstar🎓
Top SchoolKirill Vasilenko is a seasoned Senior Software Engineer and tech leader with 13+ years in backend development and 8+ years leading teams up to 20+, currently building on-disk vector database features at JetBrains. He combines deep systems and algorithmic expertise across Kotlin, Java, C#, Python and SQL with hands-on experience in cloud platforms (AWS, GCP) and high-load architectures. Notable impact includes a 10x improvement in ANN search accuracy for an inner product distance, a registration flow that boosted daily sign-ups by 30%, and designing a loyalty service handling 100M+ transactions per day. Kirill has delivered large-scale, user-facing systems—from printing 1M+ bills monthly for Saint Petersburg to performance rescues that recovered lost traffic in days. Equally comfortable designing cross-platform desktop libraries and leading distributed teams, he brings high stress resistance (once debugging from a parachute in a military plane) and a Master’s in Computer Science with a 4.0 GPA.
