You will get your vibe coded AI SaaS fixed and launched to production
Top Rated

Project details
You built your app with Lovable, Bolt, v0, Base44, Cursor, or Claude Code. It mostly works, and it will not launch: broken flows, no real deployment, auth held together with hope, a Stripe integration you do not trust. Vibe coded MVPs die here.
I am a Full Stack AI SaaS Developer, Top Rated with 100% Job Success and $40K+ earned on Upwork, with 15+ AI products shipped. Rescuing vibe coded and AI generated MVPs is one of my four core services, and the products I build run in production with real users and real billing.
The work is direct. A launch triage finds and ranks every launch blocker in your code. Fixes proceed by severity inside the tier timebox. Then production deployment on accounts you own, with a security pass, billing integrity, and LLM cost controls on Standard and Advanced.
Two fears, answered. I do not shame vibe coded work and I do not rewrite everything from scratch; salvaging what already works is the job. And the timebox cannot surprise you: if your app needs more than it covers, you get a written estimate for the rest before any extra work. Full rebuilds and new features are separate custom contracts from $5,000, never a requirement.

UX/UI Design Sprint: Wireframes, Product UI & Developer Handoff (SaaS Platform)
Outstanding from start to finish
Muhammad stepped into an incredibly complex project and took ownership from day one, which is no easy feat. He not only absorbed an extensive mid-fidelity wireframe package but elevated it beyond expectations - delivering a fully custom, high-fidelity design system and developer handoff that exceeded expectations.
He went above and beyond at every stage, producing exceptional UX/UI screens across a highly technical SaaS platform and full marketing website.
Muhammad operates at an elite level - proactive, highly collaborative, and supported by a strong team. Communication was clear, deadlines were met, and the quality of execution was consistently impressive.
A rare find. Would hire again without hesitation. Highly recommended.

About Muhammad
Full Stack AI SaaS Developer | LLM, RAG, AI Agents | MVP to Production
100%
Job Success
Rawalpindi, Pakistan - 4:41 am local time
Most AI projects die between the demo and production. The prototype works on three test files, then falls apart on real user data, real concurrency, and real edge cases. Anyone can wire up an LLM API call. I build the version that survives real users and real billing.
WHAT I BUILD
1. Full stack AI SaaS platforms Complete products: secure authentication, admin dashboards, Stripe subscriptions, credit metering, multi-tenant architecture, analytics, and cloud deployment. Security by default: RBAC, encrypted data, audit logs, and GDPR-aware architecture for compliance-heavy domains. Not a chatbot on a landing page.
2. RAG pipelines and knowledge systems Document ingestion, embeddings, vector search (Qdrant, Pinecone, pgvector), citation grounding so answers come from your documents, not generic AI knowledge, plus admin controls so non-technical teams manage the knowledge base.
3. AI agents and workflow automation Production agents for outbound sales calls, multichannel outreach, lead qualification, and document processing. Built with LangChain and LangGraph, real telephony (Twilio, ElevenLabs, Deepgram), per-lead state machines, retries, audit logs, and error handling.
4. AI integration and prototype rescue Adding LLM features to a product you already have without destabilising what works. Includes rescuing vibe-coded and AI-generated MVPs (Lovable, Bolt, v0, Base44) and taking them to stable production.

HOW I WORK
• Scope: We agree on what "done" means before I start. Written milestones, fixed deliverables, defined revision limits. I work independently from briefs.
• Build: Architecture first, then weekly demos you can click on. Daily progress updates, clear written communication, fast async responses.
• Tooling: AI-assisted development with Claude Code and Cursor, with human architecture, code review, and testing. Speed without slop.
• Handoff: Clean, documented code in a repo you own from day one. Deployment, documentation, and a system your team can maintain without me. No lock-in.
WHAT CLIENTS SAY
"Outstanding from start to finish... operates at an elite level." (SaaS platform client) "Very professional and does amazing work." (AI coaching client) "On time and professionally done. Would love to work with him again."
BEST FIT
Founders and product teams with a funded or revenue-generating product who need AI features that hold up with real users, or an MVP that needs to become production-grade. I am looking for long-term technical partnerships, not one-off gigs. Confidential and NDA work welcome. Custom builds start at $5,000; scoped audits and architecture sprints available as smaller entry points.
NOT A FIT
Single-page GPT wrappers, no-code-only builds, or projects without a defined scope.
Send me your product, your current stack, and what you want the AI to do. I will reply with a technical direction and a realistic scope, not a template.
Steps for completing your project
After purchasing the project, send requirements so Muhammad can start the project.
Delivery time starts when Muhammad receives requirements from you.
Muhammad works on your project following the steps below.
Revisions may occur after the delivery date.
Confirm scope and access in writing
We confirm in writing: the repository, the core user flows that define working, your deadline, and tier scope. NDA first if requested. I take read-only access and nothing more until fixes begin.
Launch triage: every launch blocker found and ranked
I review the code and architecture and produce a ranked launch blocker list: what stops launch, what risks money or data, what can wait. This list drives the whole order and sets the fix sequence.
