Muhammad Arafat Hossain
React Native Software Engineer

I build and ship production-ready mobile applications for iOS and Android, with a focus on scalable architecture, real-time features, payments, and performance.

Build and maintain production web and mobile applications, with a primary focus on React Native development. Work across the product lifecycle—from implementing complex features and integrating APIs to improving performance, resolving production issues, and preparing applications for release.

• Develop and maintain cross-platform iOS and Android applications using React Native, TypeScript, and Expo, with a focus on reusable components, maintainable architecture, and consistent behavior across devices.
• Build product features involving REST APIs, authentication, asynchronous data flows, and client-side state management, handling loading states, failures, retries, and edge cases required in production applications.
• Implement real-time and event-driven functionality using technologies such as Socket.io and Server-Sent Events for live updates, communication, and responsive user experiences.
• Work on performance-sensitive mobile interfaces using React Navigation, Reanimated, optimized lists, and efficient rendering patterns to keep interactions responsive across a range of devices.
• Implement and maintain payment workflows using Stripe and Square, including transaction states, validation, error handling, and recovery flows.
• Collaborate with designers, backend engineers, and product stakeholders to take features from implementation through testing and release, while contributing through Git workflows, code reviews, debugging, and continuous iteration.
