Message

At Genestack, I redesigned biological data import pipelines, taking processing time from hours to minutes. I also implemented MCP integration with LLMs for natural-language querying, increasing daily user requests by 40%.

I’ve worked on backend platforms across biotech, clinical data, KYC/AML, fintech, banking, automotive, stock trading, and gaming. At PerfectArt, I led a Scala-to-Kotlin service migration that eliminated mixed-language bugs and sped up code delivery by 30%.
