MUHAMMAD KHALID U.

I take technical ownership of your product from architecture to deployment and I stay until it works in production. I'm a full-stack SaaS engineer with 5 years of experience shipping real products used by real people. Not mockups. Not MVPs that never launch. Products like Ostool AI an Arabic fleet management platform serving 40+ enterprise clients across Saudi Arabia and UAE and Callmi, a real-time mentorship platform that reached 500 users within 6 months of launch. I work with founders who need someone they can trust with the technical side of their business, and CTOs who need a senior engineer who doesn't need to be managed. My job is to make your product work correctly, make good decisions independently, and tell you the truth when something won't work the way you've described it. What I specialise in: Full-stack SaaS products built on Next.js, NestJS, and PayloadCMS. Mobile apps in React Native and Swift. AI integrations using OpenAI and Apple Vision Framework. Cloud infrastructure on AWS. Where I'm genuinely different: MENA market development. If your product needs Arabic RTL, ZATCA e-invoicing compliance for Saudi Arabia, or regional payment gateways like SADAD and Mada I've built all of it in production. Most developers google these things. I've already shipped them. How I work: I take on a small number of projects so each client gets my full attention. I send clear updates without being asked. I flag problems before they become expensive. I make decisions independently within the agreed scope. If you need someone to tell you exactly what to build, I'll do that too I think in products, not just code. If you're building a SaaS product, a mobile app, or an AI-powered tool and need an engineer who can own it invite me to your project. First call is 30 minutes and free.
