At Polygon Afrekensystemen, I contribute to Android POS and ticketing applications, developing features and secure transaction flows with Kotlin, Jetpack Compose, and Java.
As a freelance Android Developer, I owned native apps for Getslocal's loyalty network and Raxedo.com's e-commerce app. I shipped four apps and handled architecture advice, testing, and post-launch quality.
At Timble Technologies Pvt Ltd, I built customer-facing features using GraphQL, REST APIs, Firebase, and other Android integrations. I also built and shipped a face-liveliness detection SDK for biometric authentication.
I care about testable, secure, accessible software and full lifecycle ownership. As a former team lead, I coached Android developers through code reviews and hands-on knowledge-sharing.
