I’m working as a Senior Mobile App Developer at TigerIT Bangladesh Ltd., where I’m involved in building and maintaining mobile applications for Android and iOS. My main focus is Flutter and React Native development. I work on different stages of the development process, from understanding requirements and working with UI/UX designs to developing features, integrating APIs, testing, fixing issues, and preparing apps for release. Over the years, I’ve worked on mobile applications with different requirements, including business apps, customer-facing applications, eCommerce solutions, dashboards, and apps that require third-party service integrations. I’ve also worked with Firebase, REST APIs, authentication, push notifications, payment integrations, analytics, and other external services. I work closely with designers, backend developers, QA, and other team members to make sure the final product works properly and provides a smooth user experience. I also spend time improving existing applications, fixing bugs, optimizing performance, and making sure the code remains clean and maintainable as the project grows. My responsibilities include: • Developing cross-platform mobile applications using Flutter and React Native • Converting Figma/UI designs into responsive and functional mobile interfaces • Integrating REST APIs and backend services • Working with Firebase and third-party services • Implementing authentication, notifications, payments, and other app features • Debugging and resolving technical issues • Testing applications across different devices and screen sizes • Improving app performance and overall user experience • Managing app builds and deployment for Android and iOS • Collaborating with team members throughout the development process I enjoy working on real-world products where I can understand the problem first and then build a practical solution around it. My goal is always to deliver mobile apps that are reliable, easy to use, and ready to grow
