Rizwan A.

I help businesses build iOS and Android apps, take over existing projects, and keep their apps moving forward. Whether you’re starting with Figma designs, dealing with an unfinished codebase, or fixing problems in a live app, I can handle the mobile development and the web or backend work that supports it.

I’m Rizwan, a Top Rated Plus Mobile & Full-Stack Developer with 10+ years of software development experience and $50K+ earned on Upwork. My main focus is React Native, Expo, and Flutter.

Here’s where I can help:

• Build mobile apps from designs or requirements
• Review and take over existing codebases
• Fix crashes, bugs, and performance issues
• Integrate authentication, payments, and subscriptions
• Connect APIs, push notifications, and real-time features
• Implement offline functionality, maps, background location, and camera features
• Manage TestFlight builds, App Store and Google Play submissions, and ongoing updates
• Integrate AI assistants, chatbots, and AI-powered features into mobile and web apps using the OpenAI API

My portfolio includes CarTrust, an automotive platform focused on vehicle inspections, valuations, reports, and used-car decision support. It’s an example of the practical business products in my portfolio, where clear information and straightforward user journeys matter.

For projects that need more than a mobile app, I also work with React, Next.js, Node.js, TypeScript, Firebase, Supabase, and PostgreSQL. I can integrate AI features using the OpenAI API when they solve a clear problem for your users.

When taking over a project, I first understand the codebase, your priorities, and what’s blocking progress. Then I outline a practical plan, explain the tradeoffs, and keep you informed as the work moves forward. You’ll know what’s completed, what comes next, and what needs your input.

Tell me what you’re building—or what needs fixing—and we can work out the next step.
