Message

At Kipmi Software, I develop QuantID, a digital identity wallet built with Kotlin, Jetpack Compose, and a multi-module Clean Architecture. I implemented verifiable credential sharing flows using OpenID4VP and OpenID4VC, and added wallet features including expiration reminders and account deactivation.

At MentorMate, I led mobile development, modernized a legacy application, and improved connectivity for a Bluetooth-enabled medical device. Across fintech, healthcare, e-commerce, and secure communications, I’ve delivered Android applications and worked on projects including an encrypted AOSP-based OS and a sleep apnea medical device solution.
