✅ Millions of Downloads | 70+ Clients | 100+ Projects | AI Apps | Revenue Generating Mobile App Solutions | Android & iOS Apps (Flutter)
Businesses need mobile apps that drive revenue, engage users, and scale effortlessly—that’s exactly what I deliver. With 100+ projects completed and millions of downloads, I help startups and businesses turn ideas into high-performance mobile applications.
📈 Client Success Stories & Results
🔹 Healthcare App – HIPAA Compliance & Secure Data Handling
One of our clients wanted to develop a health & fitness app but struggled to find developers familiar with HIPAA compliance. Since handling sensitive health data requires strict security and legal compliance, we built their app with end-to-end encryption, secure authentication, and full HIPAA adherence. The app successfully launched, passed compliance audits, and gained thousands of active users within months.
🔹 Revenue-Boosting App Redesign
A client had an existing app but was struggling with monetization—ads weren’t converting, and in-app purchases were barely generating revenue. We redesigned the app, optimized the paywall, and implemented better monetization strategies. Within weeks, revenue increased by 200%, and the app started turning a profit.
💡 More Than Just Development – I Help You Scale:
I don’t just build apps for clients—I have built, launched, and scaled my own apps too. This means I’ve been involved in every stage of the process, from:
✅ UI/UX Design – Creating intuitive and engaging experiences
✅ Development – Building fast, scalable, and reliable mobile apps
✅ Monetization Strategies – Implementing paywalls, ads, and subscriptions that convert
✅ ASO & Growth – Optimizing for the App Store & Google Play to drive organic downloads
When you work with me, you’re not just hiring a developer, you’re getting a partner who understands the entire journey from idea to revenue.
Let’s build an app that scales! Message me, and let’s discuss how I can help.

I've spent the last decade building and scaling software products as a CTO and co-founder. Over 100 projects shipped across SaaS platforms, marketplace platforms, mobile apps, admin dashboards, and enterprise systems.
I handle everything from Figma UI/UX design and prototyping to backend architecture to deployment. When you work with me, you get one person who owns the entire process. No coordinating between designers or developers. No miscommunication. I take your idea from strategy to a live, working product.
Here's what that actually looks like:
→ A fully designed and built product, not just wireframes or a plan
→ One point of contact who understands both the business side and the technical side
→ Honest feedback on what to build and what to skip. I'm not a yes man who builds whatever you ask without thinking about whether it actually makes sense for your business
→ Clean, scalable code that won't fall apart when you start growing
🤔 What My Clients Say:
⭐⭐⭐⭐⭐ "Abdel was easy to work with and quick to adapt. Everything works smoothly now." | The Sonderhood
⭐⭐⭐⭐⭐ "He gave us tools that made scaling possible. We can focus on growing the brand now." | Golverd
⭐⭐⭐⭐⭐ "The platform feels premium, which is exactly what we needed. The booking flow is seamless." | Lore
🚀 Selected Case Studies:
🏆 ROAP | Sports Academy Marketplace (UAE)
Built a dual-sided marketplace platform with a parent-facing mobile app (Flutter) and a full ERP admin dashboard. Multi-tenant architecture supporting dozens of academies. Scaled to 1,000+ active users across the UAE.
📍 Venu | AI-Powered Venue Marketplace
Engineered an AI search engine (OpenAI + LLMs) that lets users find event spaces using natural language. Built on Next.js with PostgreSQL. 10,000+ active users, high retention, and simplified discovery for everything from co-working spaces to wedding villas.
🔗 Bravo Link | AI Smart Notebook
Built a proprietary AI engine with OCR that converts handwriting to digital text, integrated with task delegation and calendar sync. 8,000+ professional users.
💅 Lore | On-Demand Beauty Services
Shipped a three-sided platform. Customer app, professional app, and admin dashboard. Full booking flow, real-time availability, Stripe payments, subscription systems, and review system.
👨💻 How I Work:
I handle the full lifecycle. UI/UX design in Figma, frontend, backend, deployment. You get the speed of working with one senior full stack developer without the overhead of managing a team.
⚙️ Tech Stack:
Frontend: Next.js, React, TypeScript, React Native, Flutter
Backend: Node.js, Express.js, NestJS, REST APIs, GraphQL
Databases: PostgreSQL, MongoDB, Supabase, Firebase
Payments & Infra: Stripe, billing systems, webhooks, authentication

- UI/UX Implementation
I build clean, responsive, and user-friendly screens based on your design or wireframe — optimized for both iOS and Android.
- Backend & API Integration
I connect Firebase, Supabase, custom REST APIs, OpenAI or LLM-based AI features, payment gateways, user authentication, push notifications, real-time chat, in-app purchases, and other required systems.
- Testing & Bug Fixing
I test the app on different devices, fix issues, improve performance, and make sure the app runs smoothly across iOS and Android.
- App Store & Google Play Submission
I prepare the final build, handle all store requirements, and support submission to the App Store and Google Play.
- Post-Launch Support
After launch, I can help with updates, bug fixes, new features, and long-term maintenance.
