AI-Powered Mobile Apps - Professional

For most products, yes. React Native with Expo gives you one codebase for iOS and Android, streaming AI responses through the Vercel AI SDK, camera and microphone access for vision and voice features, and over-the-air updates so prompt changes ship without a store review. I keep API keys on a backend I build for you, never on the device. Native rewrites only make sense for heavy on-device inference or hardware integrations.

Yes, within limits. Small language and speech models run on modern phones with ExecuTorch, llama.rn or Core ML, which is what my Enterprise mobile tier uses for privacy-sensitive features and offline use. Larger models still belong in the cloud. The usual design is hybrid: on-device for transcription, classification and quick replies, cloud for anything that needs a frontier model, with a router that picks per request.

I'm a freelance AI product developer from Rajshahi, Bangladesh, working under the name Mursalin's Desk. I build AI agent SaaS products, AI-powered mobile apps with React Native and Expo, MVPs for startups, AI integrations for existing products, and full-stack web platforms on Next.js, NestJS and PostgreSQL. I also take on AI strategy and fractional CTO engagements for founders who need senior technical leadership without a full-time hire.

I'm based in Rajshahi, Bangladesh, and also work from Dhaka. Most of my clients are remote — startups and small companies in the US, UK, Canada, Australia and the EU. I can meet in person in Rajshahi or Dhaka when that helps, but every project I run is set up to work fully remotely from day one: shared repo, project board, async updates and scheduled calls.
