Here’s a polished paragraph combining your responsibilities and achievements, with a bit of enhancement for impact: I develop and maintain high-quality Android and Flutter applications using modern technologies such as Kotlin, Jetpack Compose, Dart, and architectural patterns like MVVM and Clean Architecture. I have built and optimized core business features including booking flows, seat selection, ticketing, payment integration, and trip management systems, ensuring seamless user experiences. I integrate and manage RESTful APIs using Retrofit, OkHttp, Gson, Coroutines, and Kotlin Flow, while also leveraging Firebase services such as Crashlytics, Remote Config, Analytics, and FCM to monitor app performance, improve stability, and enhance user engagement. I design and implement scalable, reusable UI systems with consistent design tokens, themes, and typography, contributing to maintainable and efficient codebases. Additionally, I actively diagnose and resolve production issues including crashes, performance bottlenecks, and complex network/SSL problems. I manage end-to-end app release processes on the Google Play Store, including signing configurations, ProGuard/R8 optimization, and mapping file handling. I also collaborate closely with cross-functional teams—including design, backend, QA, and product—to deliver robust, user-centric features on time. Beyond development, I contribute to code reviews, technical decision-making, and continuous improvement of development workflows, ensuring high standards of code quality, scalability, and performance across projects.
