Senior Android developer specializing in secure fintech and healthcare apps, NFC tokenization, and Clean Architecture multi-modules.
What I'm looking for
I’m a Senior Android Engineer with 9.4 years building secure fintech and healthcare apps, plus SDK integrations, in Kotlin and Java. I focus on turning complex payment and platform requirements into reliable, testable mobile systems.
At TECHOLUTION INDIA, I spearheaded Mastercard/Visa NFC card tokenization for the “Juice” banking app, increasing contactless payment adoption by 40%. I applied cryptography-focused security considerations across payment and tokenization flows to help protect sensitive transaction data in a regulated environment.
I also re-architected legacy apps into Clean Architecture multi-module projects using Jetpack Compose and CI/CD, improving release velocity by 30%. I paired that with MockK + JUnit unit/integration testing to reduce regression bugs across critical financial transaction flows.
Previously, at EKINCARE, I delivered 6+ major production releases with zero critical crashes, raising Google Play Store rating from 3.8 to 4.5. I modernized UI with Jetpack Compose (35% faster screen load times), built modular health dashboards using MVVM, and earned a Service Excellence Award for consistent code stability.
