About Subham Kumar Mishra

I build and maintain production mobile applications used in real operational environments.I develop applications using React Native and native iOS technologies (Swift and SwiftUI), where my work involves structuring screens and navigation flow, integrating REST APIs, handling asynchronous data, and managing application state to ensure consistent behavior across devices.At Rentilium, I delivered live applications including a Tenant App and a Business ERP platform that manage operational workflows such as rent collection, tenant communication, maintenance tracking, and financial records. Since these applications handle real users and transactions, the implementation required careful error handling, retry logic, and data synchronization between the app and backend services.I integrated secure authentication, local secure storage, push notifications, and background processes required for real-time updates. I also implemented payment workflows using Razorpay and PayU, covering order creation, payment confirmation, failure handling, and transaction verification with backend reconciliation.Along with development, I handle release preparation and maintenance — generating production builds, configuring certificates and provisioning, managing versioning, publishing on Google Play Store and Apple App Store, and delivering post-release updates and fixes.I focus on writing clear and maintainable code with modular structure so the application remains stable, debuggable, and reliable after deployment.
