At Paytm, I build Android wallet add-funds flows with the Alviere SDK and apply a mobile security stack that includes encryption, SSL pinning, and Play Integrity. I also designed AI workflows that validate Jira tickets and enrich requirements before development begins.

At Startele Tech Pvt Ltd., I built the Flash Call SDK for OTP-less authentication, which reached 10K+ active users, and developed VoIP Android apps. I also migrated a legacy codebase to Kotlin, MVVM, and Jetpack Compose, and led a three-member team.
