Über mich
Hi, I’m Nazarii, a Full Stack Developer from Ukraine focused on fixing, deploying, and extending Next js apps.
I help founders and small teams with Next.js bugs, Vercel or Render deployment issues, Node.js errors, API integrations, Stripe billing, Supabase, OpenAI features, dashboards, and lean SaaS MVPs.
If you have an existing app, repo, or product idea, I can help debug the issue, connect the missing piece, or get the app live with clean code and clear communication.
