Project details
Built something with Lovable, Bolt, Replit, or v0 but now it's broken and you can't fix it? You're in the right place.
I'm a senior full-stack developer with 7+ years of experience. I built a SaaS platform from zero to $1M+ ARR. I take vibe-coded prototypes and turn them into production-ready apps that actually work.
What I fix: Auth and login errors (Supabase, Firebase, Clerk) Broken database connections and RLS policies API integration failures Deployment errors on Vercel, Netlify, or AWS Features that break other features App crashes and performance issues
What I build from your prototype: Connect a real database (Supabase, PostgreSQL, Firebase) Add proper authentication and user management Build missing backend logic and API routes Deploy to production with custom domain and SSL Add payments with Stripe Scale from prototype to real product
I work with: Lovable, Bolt.new, Replit, v0, Cursor, React, Next.js, Supabase, Firebase, Node.js, Vercel, AWS.
Message me with a link to your project or a screenshot of the error. I'll tell you exactly what's wrong and how long it will take.

GEO Audit Needed — Driving School Site Visibility Across ChatGPT, Gemini,(Full Report + Action Plan)
Hired Jahanzaib for a GEO audit of our driving school site — wanted to know where we stood inside ChatGPT, Gemini, and Perplexity. He delivered exactly what we asked for.
The report wasn't a generic SEO checklist. He actually tested our brand across all the major AI engines, mapped which sources LLMs cite for our niche, benchmarked us against competitors who ARE showing up in AI answers, and gave us a prioritized action plan we can actually execute. The competitor source-mapping piece was the most useful part — none of the other audits we looked at went that deep.
Knows GEO and AI search inside out. Will be coming back to hire him for the implementation phase. Recommended for anyone serious about AI visibility.

Senior Engineer — Fix Lovable + Supabase + Stripe SaaS with AI Voice Agent (ElevenLabs)
Really solid work from Jahanzaib on this one. Our Lovable + Supabase app was crashing every time the ElevenLabs voice agent triggered and we had no idea where to start. He diagnosed the race condition in his very first message which gave us confidence right away.
Fixed all the bugs we listed — voice agent crash, ElevenLabs context retention, Stripe webhook chain, Supabase RLS, plus cleaned up the Lovable code and deployed properly to Vercel. Communication was clear, no fluff, and he stuck to the hours he estimated.
Strong full-stack + AI engineer. Will definitely hire again for the next phase. Recommended.

THE FIX LANE — if you vibe-coded an MVP and it's 80% done, half-broken, or scary to launch, that's my lane. I take Lovable, Bolt, Replit, Base44, and Cursor builds to production: auth that actually protects user data, Stripe billing that doesn't double-charge, Supabase row-level security, clean deploys, App Store releases. My latest 5.0 review was exactly this — a Lovable + Supabase + Stripe app that crashed every time its ElevenLabs voice agent fired. Found it, fixed it, shipped it.
THE BUILD LANE — if you're starting from scratch or scaling:
- SaaS MVPs: React/Next.js, Node, PostgreSQL/Supabase, Stripe, deployed on AWS (Lambda, S3, ECS). Typically 6–12 weeks to first paying customer.
- AI agents & integrations: OpenAI and Claude APIs, RAG over your data, custom MCP servers (I built one with 13 tools running against a live HR database), and voice agents with Vapi, Retell, and ElevenLabs.
- Mobile: React Native — FoodSwitch (400k+ downloads), reSTASH (1,500+ users with live bidding).
How I work: every Upwork contract is me, solo — I write the code, run the calls, and ship the releases myself. (I take occasional part-time work through a software agency, which is the association you'll see on my profile, but nothing here gets passed to a team.) I reply within 2 hours during EU/US business overlap, push code daily, and keep a clear paper trail in Linear or Jira. Fixed price for scoped slices, hourly for ongoing work.
First call's free — and if your project turns out to be a Zapier job or a 30-minute fix, I'll tell you that instead of selling you a build.
Steps for completing your project
After purchasing the project, send requirements so Jahanzaib can start the project.
Delivery time starts when Jahanzaib receives requirements from you.
Jahanzaib works on your project following the steps below.
Revisions may occur after the delivery date.
Audit, fix and rebuild
I'll audit your app, identify all bugs and missing pieces, then fix broken features, connect the database, set up auth, and refactor any code that won't scale to production.
Deploy and handoff
Deploy to production with your custom domain, run final QA, and hand off with source code, deployment docs, and instructions so you can manage and extend the app yourself.
