About

Hi, I'm Stan

I'm a senior frontend developer and tech lead based in Tallinn, Estonia. For 13 years I've built web applications in React and TypeScript — most recently leading frontend teams on enterprise media platforms, with Node.js microservices on the backend.

NGINE is my contracting studio. I work directly with founders, agencies and product teams across Europe and the UK — remotely or on site in Tallinn.

Senior from day one

13 years of production experience means less ramp-up and fewer surprises.

Enterprise-tested

Background in large media platforms where performance and reliability are non-negotiable.

Product-minded

I build and run my own products, so I care about outcomes, not just tickets.
