Kosta Korenkov is a hands-on CTO and seasoned software engineer with 12+ years building distributed web and blockchain systems from architecture to production. Based in Montenegro, he has launched interconnected products for the film industry, including an EVM on-ramp, scalable video-on-demand infrastructure and Ethereum payment smart contracts, and currently leads White Rabbit and YouStar. He brings deep crypto experience—contributions to bitcoinj, Bitpay/Bitcore, and Truffle show a track record across wallets, UTXO handling and developer tooling—and helped build one of the early Ethereum Layer-2s at LeapDAO. Equally comfortable in front-end UX work (Timestripe, Bitpay UI) and backend protocol logic, he blends TypeScript/Node.js, React, GraphQL, AWS and Solidity to ship end-to-end solutions. Collected experience from startups to enterprise team leadership gives him a pragmatic, product-focused approach to scaling systems and teams.
