Project details
Need to launch an AI SaaS product or add AI features to an existing app?
I build production-ready AI SaaS applications using Next.js, React, Node.js, TypeScript, Supabase, PostgreSQL, Stripe, and AWS. I can take your product from requirements and architecture through development, AI integration, deployment, and stabilization.
This project is suitable for:
• AI SaaS MVPs
• AI agents and RAG assistants
• AI-powered dashboards and internal tools
• OpenAI, Claude, or Gemini integrations
• Subscription or credit-based platforms
• Existing AI-generated apps that need senior engineering
Recent work includes a SaaS platform integrating 65+ AI models, a Claude MCP agent connected to live inventory and financial data, and the rescue of an AI-built platform processing multi-terabyte datasets.
You will work directly with a senior full-stack engineer with 10+ years of experience.
Please message me before purchasing the Standard or Advanced package so I can confirm that your scope, integrations, and timeline fit the selected tier.

30 minute consultation
Great experience working together. The developer quickly understood our existing MVP, identified the key production-readiness risks, and gave us a clear, prioritized roadmap around security, scalability, performance, architecture, and next steps. Communication was professional and the recommendations were practical and actionable.

About Hammad
Sr Software Engineer | AI-Generated App Rescue (Lovable, Bolt, Replit)
100%
Job Success
Karachi, Pakistan - 2:43 pm local time
Lovable, Bolt, Base44, Replit, Cursor, and Claude Code can get you a working app fast. But when it starts breaking under real users, you need someone who can read the code, understand the architecture, and fix the root cause, not just prompt around it.
That's what I do: build, audit, repair, and productionize AI SaaS applications.
With 10+ years of full-stack engineering experience, I've delivered everything from founder-led MVPs to enterprise platforms, and today I apply that experience to AI-generated applications that need to perform in production.
Six weeks in, a feature breaks, an API call starts failing, performance drops, or the "vibe coder" who built it stops replying. That's when I step in.
I work across the full stack: Next.js, React, Node.js, TypeScript, Supabase, PostgreSQL, Stripe, AWS, and AI integrations including Claude, OpenAI, Gemini, LangChain, LangGraph, MCP, and vector search.
Recent rescue work:
* Rebuilt an AI-generated acoustic analysis platform to handle multi-terabyte research datasets, improving data retrieval by 5x and file loading by 240%
* Built an MCP-powered Claude agent that lets a wholesale business query live inventory, customer balances, sales trends, and profitability in plain language
* Engineered a production AI SaaS platform integrating 65+ text, image, audio, and video models across nine providers
* Took over and launched an unfinished fitness marketplace across web, iOS, and Android with Stripe subscriptions, bookings, and QR check-in
WHAT I FIX:
* Authentication and session issues
* Supabase, PostgreSQL, and database problems
* Slow queries and performance bottlenecks
* AI integrations, agents, RAG, and API failures
* Stripe, subscriptions, and payment flows
* Deployment failures on Vercel, AWS, and other platforms
* Exposed secrets, weak permissions, and security gaps
WHAT YOU GET:
* A direct diagnosis before any fix starts, no shortcuts stacked on shortcuts
* Senior-level technical ownership, not isolated development tickets
* Milestone updates at every stage, not just a final reveal
* 30 days of post-delivery support included
The worst part of a broken app isn't the bug. It's not knowing whether you're looking at a 10-minute fix, an architectural problem, or a full rebuild.
Send me your app URL, codebase, or requirements. I'll tell you what should be retained, repaired, rebuilt, or simplified, and what it will cost before you commit to anything.
Steps for completing your project
After purchasing the project, send requirements so Hammad can start the project.
Delivery time starts when Hammad receives requirements from you.
Hammad works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & Requirements
I understand your vision and goals, then create a detailed PRD covering features, user flows, and success criteria — so we're aligned before any code is written.
System Architecture & Database Design
I design the technical architecture (frontend, backend, APIs, integrations) and database schema to support scalability, security, and your specific SaaS requirements from day one.
