Full-Stack Developer (Next.js, NestJS, MySQL) for AI-Powered Restaurant Management SaaS
It’s not often you find a Full Stack Developer who feels like a partner, not just a hire. Working with Muhammad has been an excellent experience. I brought him on to build the MVP of my SaaS and he went far beyond expectations. He quickly spotted gaps, suggested improvements I hadn’t even considered, and delivered ahead of schedule. He’s independent, clear in communication, and genuinely takes ownership of the work. Easily one of the best Full Stack Developers I’ve worked with.

Karachi, Pakistan - 1:14 pm local time
Most founders hire a "developer" when they actually need an AI systems architect — someone who designs the full stack: the agent logic, the data flow, the business rules, and the automation backbone.
That's why 80% of AI projects never make it past the demo stage.
