Job Success
Gujranwala, Pakistan - 12:59 am local time
Most AI SaaS products die at the unglamorous part. Retrieval that returns the right document instead of a confident wrong one. Token costs that do not triple in month three. Ai Agents that recover when a tool call fails instead of hallucinating forward. That is the part I get hired for.
I build end to end AI SaaS products with production ready infrastructure. The app, the AI layer, billing, auth, scaling, the parts your customers actually touch. Wiring up an OpenAI call is a weekend. Everything around it is the product, and I have shipped it enough times to know where it breaks.
WHAT I HAVE SHIPPED
SellAgent.ai - AI SaaS sales automation platform. AI voice agent that calls leads the moment they come in, automated follow up sequences, pipeline management. Built end to end.
Keystone Equities - Ai based operating system for a commercial real estate equity firm. Broker outreach workflow, automated deal intake, AI analysis of offering memorandums, and deal-to-investor matching. Also built an AI voice agent that answers inbound calls, holds the lead in conversation, and follows up until the deal moves. They went from closing 1-2 deals a month to over 25.
WhisprBot - AI SaaS messaging platform taken from empty repo to live users. Real-time architecture, multi-tenant, running in production.
FlightConnections - interactive world map handling route rendering and spatial data at scale. Performance work on large geographic datasets in the browser.
GarageCycles - e-commerce build with a custom inventory and pricing sync against a supplier that had no native integration available. Plus Strava API and Mapbox integrations, all live.
eSIM provisioning middleware - NestJS service handling carrier provisioning flows and third party API orchestration.
CVS Health - enterprise automation under real compliance constraints. CI/CD pipelines, PowerShell tooling, source control migration. This is where I learned what shipping looks like when the review process is serious.
Plus takeover and rescue work on codebases left behind by previous developers and by no-code tools including Lovable, Bubble and Replit.
REACH OUT IF
You have an AI SaaS idea and want the MVP built right the first time. Something you can put in front of paying customers, not something you throw away in six months when it will not scale.
You run a working SaaS and want AI features inside it that do real work. Document processing, intelligent search, agents that complete tasks. Not an AI chatbot bolted onto the corner of the dashboard.
Your AI SaaS works in testing and breaks in production. Hallucinations, latency, token bills climbing every month, agents that stall halfway through a task. All of this is fixable and I have fixed it.
You inherited a codebase from a previous developer or a no-code platform and need someone to take it over, stabilize it, and keep building on it.
You want a technical partner rather than a task-taker. I will tell you when a feature is a bad idea before I build it, not after.
NOT A FIT IF
You are shopping for the lowest hourly rate on the platform. You need a model training or fine-tuning specialist rather than someone who builds the product around the model. You want someone who codes exactly what the ticket says and nothing more.
HOW I WORK
Scope agreed before anything gets built. Working software you can click on early, not a status report. Direct communication with comfortable US hours overlap. Clean code and documentation handed over, so you are never held hostage by the person who built it.
