Karachi, Pakistan - 2:12 pm local time
and generate revenue — working with startups, SaaS founders, and growing businesses
across North America, Europe, and the Middle East.
My core stack: React Native (iOS & Android), the MERN stack (MongoDB, Express,
React, Node.js), and AI integrations using OpenAI/ChatGPT. I've shipped products
in FinTech, EdTech, Healthcare, Fitness, and eCommerce — and I know exactly where
mobile projects break down before launch.
━━━━━━━━━━━━━━━━━━━━━━
🔧 WHAT I BUILD
━━━━━━━━━━━━━━━━━━━━━━
📱 Mobile Apps (iOS & Android)
Cross-platform apps in React Native or Flutter — or native Swift/Kotlin when
performance demands it. Includes full App Store & Google Play submission.
🌐 Web & SaaS Platforms
Full-stack MERN applications, multi-tenant SaaS products with subscription billing,
role-based access control, and admin dashboards.
🤖 AI-Powered Features
ChatGPT/OpenAI integrations, AI chatbots, smart recommendations, and LLM-driven
workflows embedded into your mobile or web app.
☁️ Backend & APIs
REST and GraphQL APIs, Firebase, AWS (EC2, S3, Lambda), real-time features with
WebSockets, and payment integrations (Stripe, Braintree, Apple Pay, Google Pay).
━━━━━━━━━━━━━━━━━━━━━━
⚙️ HOW I WORK
━━━━━━━━━━━━━━━━━━━━━━
1. Discovery → I scope your requirements, propose a tech stack, and define milestones
before writing a single line of code.
2. Prototype → Wireframes and architecture sign-off so we're aligned on UX and flow.
3. Build → Bi-weekly demos keep you in the loop — no black-box surprises at launch.
4. QA & Deploy → Manual + automated testing, crash tracking (Crashlytics/Sentry),
staged rollouts, and App Store/Play Store submission.
5. Post-Launch → 30 days of free maintenance, with optional long-term retainer support.
