👨‍💻 Professional Summary I am a seasoned software engineer with over 13 years of experience specializing in video streaming, web development, and mobile application development. Throughout my career, I have architected and delivered custom solutions for: Video transcoding and live recording Video conferencing and real-time chat IP camera and IPTV channel restreaming Interactive media applications and rich video UIs My development philosophy emphasizes starting with a proof of concept (PoC) or live demo to ensure mutual clarity and alignment before initiating full-scale implementation. This approach consistently helps streamline project expectations and delivery. 🎓 Academic Background Postgraduate Degree (2007) Began my professional career working with Java EE technologies including Struts, Spring, and Hibernate. 📱 Mobile & Real-time Communication Experience Developed core Android applications since 2010 Built XMPP-based chat apps for iOS Integrated real-time communication systems using WebRTC, Socket.IO, and Node.js 🎥 Video Streaming Expertise Hands-on experience with major streaming platforms including Wowza, Red5, and Adobe FMS since 2009 Built custom WebRTC-based solutions using Node.js, React.js, Socket.IO, Livekit and HTML5 Developed tools with Fabric.js for HTML5 canvas-based video editing and live drawing overlays 💡 Work Ethic I believe that dedication, transparency, and an honest effort are key to achieving successful outcomes. I continuously strive to adopt evolving technologies that enhance end-user experience and system performance.

I am a software developer working as a software developer/architect in chat-related products. I have started my experience with AnyConnect, and now I am continuing as an independent freelancer. I am working with the XMPP server for the last 5 years . I have worked closely with the Ejabberd server, which WhatsApp initially used. Having working experience with this server for this many years i can modify XMPP module as per customer needs and add a new API to satisfy every customer needs. I have developed many Chat applications based on XMPP, FCM having the following features with Native Android/Ios and Flutter. - One - One chat. - Group Chat. - Broadcast Chat. - Text Message,Media message(text,image,audio,video,location,RIch URL,Documents),Edit,Delete,Delete for all. - Apple APNS notification and FCM messages. - Sharing content from third-party apps. - Secret Chat. - Task /Topic Management - Group management functions. - VOIP/WEBRTC-based audio/video calling. - Data Notification with doze mode. - Room based audio - video calling (EX. Bigo, starchat) I have good experience writing the unit test for better and speedy diagnosis and better development testing with following good java doc comments, which is very useful while working with a team and better documentation. I do have experience of SQL database and having used this both client and server-side so I better know the advantages/disadvantages and how to deal with the limitations. I've also contributed/developed opensource xmpp client and Libraries. Thanks, Mir Injamamul Ibne Kashem

As a Senior Mobile App Developer, I design and ship production apps for iOS and Android. My core stack as a Mobile App Developer covers React Native, Flutter and native Android (Kotlin) — 20+ commercial apps delivered across fintech, logistics, maps and social, from first commit to App Store and Google Play release. I cover the full cycle: architecture, feature development, testing, performance optimization and post-release support. Most of my work is either Mobile App Development from scratch or taking over an existing codebase that needs to become stable, fast and maintainable. Clients typically hire me as a Mobile App Developer when they need: • Mobile App Development from scratch — React Native, Flutter or native Android, shipped to both stores • iOS Development and Android App Development from a single cross-platform codebase • iPad App Development and tablet-ready layouts alongside the phone build • API Integration — REST and GraphQL backends, third-party SDKs, user authentication • Firebase integration — Crashlytics, Analytics, Cloud Messaging, Remote Config, A/B testing • Crash fixes, ANR and performance optimization on an app that is already live • In-app purchases, subscriptions and release automation for App Store and Google Play Technologies I work with as a Mobile App Developer: Cross-platform — React Native (JavaScript, TypeScript, Redux, Expo) and Flutter (Dart, BLoC, Riverpod, Provider, GetX). Native Android — Kotlin, Java, Jetpack Compose, Android SDK, Coroutines and Flow, Dagger/Hilt, Room, Retrofit, OkHttp. Backend and integrations — API Integration, REST, GraphQL, Firebase, user authentication, push notifications, in-app purchases, analytics. Architecture and quality — MVVM, MVP, Clean Architecture, mobile app testing with JUnit, Mockito, Espresso and Robolectric, Git (GitHub, GitLab, Bitbucket). I use AI as a productivity tool to speed up repetitive engineering work, but I never deliver raw AI-generated output — every line is reviewed and tested. If you need a Senior Mobile App Developer who can build a new app, rescue a struggling one, or take an existing product from prototype to a stable store release — send me a message with a short description of your project.
