At Visiontek – Linkwell Telesystems Pvt. Ltd., I develop and maintain Android and POS applications for banking, telecom, and utility clients. I work with Java, Android SDK, MVVM, and Clean Architecture.
For international banking clients, I’ve worked on secure POS applications supporting financial transactions, customer onboarding, biometric authentication, and encrypted data handling. I also integrate RESTful APIs for transaction workflows.
On electricity utility applications, I built features for offline use, local storage with SQLite and Room, and API synchronization. I’ve also contributed to eSIM management modules covering authentication, API integration, and device compatibility.
I’ve improved UI rendering through RecyclerView optimization and memory management, and worked on debugging, crash analysis, and stability improvements. I use Android Studio, Gradle, and Git in Agile/Scrum development and CI/CD release workflows.
