I’m a senior full-stack engineer with 9+ years building React/TypeScript applications, Node.js APIs and reusable SDKs. I’m looking for remote senior frontend or full-stack roles in wallets, fintech, developer tools and AI-enabled software.

At Vultisig (Aug 2024–Sep 2026), I built desktop wallet foundations and architecture shared by desktop and browser-extension clients. Wallet logic I wrote became the foundation of the Vultisig SDK, which I also helped maintain.

At Terraform Labs (Mar 2022–Jul 2024), I led Enterprise Protocol’s full-stack implementation through launch: a Next.js app, Node.js API and DynamoDB-backed indexer. The governance and treasury product’s holdings peaked at approximately $65M. I also contributed to Anchor Protocol’s React frontend and built frontends for two NFT protocols.

Earlier, I built Lace wallet features at IOG (Sep 2021–Feb 2022), wallet integrations and exchange interfaces at Zerion (Oct 2020–Aug 2021), web/mobile banking and Node.js features at Kontist (Jul 2019–Sep 2020), and React/Node.js systems at KREO (Apr 2017–Jun 2019).

My independent work includes an AI-agent harness and task dashboard for coding, review and browser QA, Increaser, and RadzionKit. I share full-stack engineering and AI development workflows on YouTube.

Education: Informatics and Programming Technologies — Engineer–Programmer, Belarusian State University of Informatics and Radioelectronics, 2015–2020.
