Hi, I'm Jeya Sheelan J
Software Engineer with 2+ years of experience crafting high-performance cross-platform mobile apps with Flutter, native hardware integrations, and transitioning into modern Native Android development with Kotlin & Jetpack Compose.
About Me
I am a passionate Mobile Application Developer with 2+ years of experience engineering high-performance cross-platform applications and integrating enterprise hardware systems.
Having built and shipped production Flutter applications powered by Bloc/Cubit state patterns and low-level Method Channels for Zebra RFID readers, I am actively channeling my expertise into Native Android development with Kotlin, Jetpack Compose, Kotlin Flow, and Material 3 design systems.
Holding a degree in Electronics and Communication Engineering (CGPA 8.3), I unite hardware-level protocol consciousness with modern declarative mobile architecture to deliver responsive, fault-tolerant, and user-centric software.
