You will get AI SaaS MVP with Next.js, Auth, and One Core AI Feature
Rising Talent
Project details
I will build a focused AI-powered SaaS MVP so you can validate your idea with real users instead of staying in the concept phase.
What's included:
• Modern landing page explaining your product and value proposition
• User authentication using Clerk or NextAuth
• Basic account area or dashboard
• One core AI feature, such as document Q&A, content generation, workflow assistant, summarizer, or internal knowledge assistant
• PostgreSQL database setup for users and core app data
• Integration with OpenAI, Claude, Gemini, or DeepSeek for the core feature
• Deployment to Vercel or similar hosting using your account
Tech stack: Next.js, TypeScript, PostgreSQL, modern UI, and LLM APIs.
You will receive clean, production-focused code that you can continue to build on, not throwaway prototype scripts.
This offer is based on my experience shipping AI products as a solo developer, including Cold Lead Decoder, a live LLM app with structured outputs, Zod validation, repair retries, degraded states, prompt-injection boundaries, and production metrics.

About Nika
Next.js & Supabase Developer | Vercel Deploys | Stripe & AI App Fixes
Tbilisi, Georgia - 3:31 am local time
I work in your stack: Next.js, Supabase, Vercel, OpenAI and Claude. I start from your repo and the exact breakage, not a rebuild.
Built it with Lovable, Bolt, v0, Cursor, or Replit? The tool layer rarely matters. Underneath it is Next.js, Supabase, and Vercel, my daily stack.
Common fixes:
- Users logged out on refresh (Supabase auth, @supabase/ssr, session flows)
- OAuth redirect and login loops
- RLS policies blocking real users
- Vercel build, deploy, and env var failures
- Stripe webhook failures
- OpenAI, Claude, and Gemini integration failures
How I work: you get a fixed quote on a small scope before any work starts. The fix ships as a pull request with a short note on what was wrong. I fix what you have, no rebuild pitch.
Proof: my portfolio includes a live Next.js 14 + Supabase marketplace for Georgian local food producers. It uses RLS policies, auth flows, and production deploys on Vercel, the same stack this profile is about. When your app hits a Supabase auth error, a failing deploy, or a Next.js bug, I bring the same production-debugging patterns to your repo.
I also debug LLM integrations (OpenAI, Claude, Gemini).
Send the repo link or the exact error message and where it appears, and I'll tell you what I'd check first before you commit to anything.
