I lead full-stack teams building TypeScript, Node.js, Web3, and DevOps platforms.
What I'm looking for
I've led full-stack engineering teams at Network Group, Equilibrium | EQ finance, EPAM Systems, and Qoden Technologies, delivering products across e-commerce, finance, Web3, and developer platforms. At Network Group, I led authentication, CI, monorepo, deployment, and process improvements that reduced pull-request review time to an average of one day or less.
I've built Nest.js and TypeScript backends, React and Next.js applications, browser extensions, DeFi integrations, and blockchain-powered products including Slender and Marginly. I enjoy tackling challenging problems, learning new technologies and domains, and helping engineers grow through documentation, 1-on-1s, learning plans, and technical screencasts.
