Sergey K.

Full-Stack Web Developer | Business Websites & Web Applications

Hi, I'm Sergey. I build and fix websites and web apps. Work I take on: - Full-stack: Next.js / React + Node.js APIs, auth, payments, integrations - CMS work when that's what the project needs: WordPress, Squarespace, sometimes Webflow or Tilda - I can build from your Figma file, or from a brief if that's all you have - Updates and forms on a site that's already live When we're done, your team should be able to change copy and pages without me. Written scope, preview links, milestones. Updates in Upwork messages. I check the site on a phone and that the form actually sends before I call it done. Live sites are on my profile. I use React, Next.js, TypeScript, Node.js, PostgreSQL, Vercel - or I stay on the CMS you already have.
