Job Success
Karachi, Pakistan - 8:10 pm local time
10+ Years of experience 20+ AI products shipped. 2 startup exits.
Why me? Product Manager to AI Consultant & Full Stack Engineer! Not your average engineer!
I don't just build AI; I architect complete systems from strategy to deployment. Most AI freelancers code. I plan, build, ship, and scale.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHO I WORK WITH
Founders building their first AI product who need someone who's done it before.
Funded startups scaling from MVP to production with real users.
Enterprise teams adding AI to existing systems without breaking what works.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT MAKES ME DIFFERENT
→ Founder + PM + Engineer in one person
I've raised funding, built teams, and shipped products from zero. I think like a founder, plan like a PM, and execute like an engineer.
→ Hubspark Consulting (USA)
I spent years advising enterprise clients on technology strategy before building my own AI company.
→ End-to-end ownership
I don't hand off half-built prototypes. I deliver working systems in production—with documentation, support, and a plan to scale.
→ (Top Rated 1% on Upwork)
100% Job Success. 10+ years. The track record speaks for itself.

HOW I WORK
Phase 1: Discovery (Free)
We talk. I understand your problem, your users, your constraints. I tell you honestly if I'm the right fit.
Phase 2: Architecture & Roadmap
Before writing code, I define what we're building and why. You get a clear plan, timeline, and milestones.
Phase 3: Build & Ship
I build in 2-4 week sprints. You see progress weekly. Working software, not status updates.
Phase 4: Launch & Support
I don't disappear after delivery. 30-day support included. Optional retainer for ongoing development.
