About

Alexey brings the backend, interface and integrations together into one working product. With six years of full-stack experience, he builds with Node.js, NestJS, React and TypeScript, extending that work into React Native apps, Chrome extensions and AI integrations. His range across Firebase, MySQL and SQL Server helps connect product features to the data they depend on. He has shipped commerce checkout flows and healthcare dashboards across client and server code. A strong fit when your roadmap crosses web, mobile and browser tools and you need an engineer who can work across those boundaries.
