About

I’m looking for a remote senior frontend or full-stack engineering role where I can own delivery across React/TypeScript interfaces, Node.js APIs and reusable systems. Wallets, fintech, developer tools and AI-enabled software are strong fits. I value clear goals, practical collaboration and responsibility from technical design through release. I’m a senior full-stack engineer with 9+ years of experience building TypeScript products, from React interfaces to Node.js APIs and reusable SDKs. I take ownership of architecture, implementation and delivery across wallets, DeFi, banking and developer tooling. At Vultisig, 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. My work covered interfaces, application logic, chain integrations and MPC signing. At Terraform Labs, I led Enterprise Protocol’s full-stack delivery from concept to launch: a Next.js app, Node.js API and DynamoDB-backed indexer. Its treasury holdings peaked at approximately $65M. I built an AI-agent harness and task dashboard coordinating planning, implementation, review and browser QA. My independent projects include Increaser and RadzionKit, and I share full-stack engineering and AI development workflows on YouTube. Core stack: React, TypeScript, Next.js and Node.js. Additional experience includes React Native, GraphQL, PostgreSQL and DynamoDB. I’m looking for remote senior frontend or full-stack engineering opportunities.
