You will get an AI or LLM feature built into your Next.js and Supabase app
Top Rated
Project details
I add AI into apps that are already live, without breaking what works. Most AI features look fine in a demo and fall apart on the second request. Mine handle the slow calls, the failed calls, and the empty states, so your users never hit a broken screen.
I work directly in your Next.js and Supabase codebase and match your existing style, so what I hand back looks like your own team wrote it. Depending on the tier, that means a clean OpenAI, Claude, or Gemini feature, streaming with tuned prompts, or full retrieval over your own documents with vector search on Supabase.
Before I start, I write the exact deliverable and acceptance criteria into the order. If the finished work does not meet that scope, I revise until it does or you do not pay. That takes the risk of hiring someone new off your side of the table.

Senior Next.js dev to fix Supabase RLS + multi-tenant data leak
Furqan is a sharp full-stack developer who fixed a nasty multi-tenant data leak in our Next.js and Supabase app. Tracked the RLS issue down to the real root cause, fixed the row-level security properly, and sanity-checked the rest of our auth flow while he was in there. Careful work on a live production app, clear explanations, and genuinely good security instincts. Highly recommended.

Job Success
Faisalabad, Pakistan - 10:08 am local time
6+ years full-stack Developer, Top Rated on Upwork. I work AI-native with Claude Code and Cursor daily, so I ship faster and clean up messy code faster than teams doing it by hand.
WHAT I BUILD
- AI and LLM features: OpenAI, Claude, and Gemini, plus RAG, vector search, agents, and agentic workflows
- Full-stack SaaS in Next.js (App Router), React, TypeScript, and Tailwind / shadcn/ui
- Supabase and PostgreSQL: auth, row-level security, and multi-tenant architecture
- Stripe billing done right: subscriptions, webhooks, and metered plans
- Taking over live codebases: audit, stabilize, then extend with AI
TAKING OVER AN EXISTING BUILD
A lot of my work as a Full-Stack Developer is inheriting something that already exists. I start by auditing what's there and telling you the honest state of it. I ship a few low-risk quick wins first, so you see progress and I earn trust. Then I stabilize the fragile parts, and only then extend with new AI features. The rule the whole time: don't break what's live.
RECENT WORK
- A large multi-tenant hospitality SaaS for a German client, roughly 58 interconnected subsystems
- An autonomous AI content-agent platform with Stripe subscriptions
- An AI document intake tool with automated extraction (Loom walkthrough available)
- AI scraping and lead-enrichment pipelines
HOW I WORK
I take ownership and ship without hand-holding. I communicate clearly and often, and I don't go quiet. I don't push risky changes to production without a rollback plan. Most clients start with one project and keep me on long term.
MY GUARANTEE
We scope a clear first milestone. If I don't deliver it to the spec we agreed, you don't pay for it. That takes the risk of hiring an unknown off your side of the table.
Tell me what you're building and where it's stuck, and I'll tell you honestly whether I'm the right person for it.
