Projects
Balloon Blaster
Demo · In developmentA browser-based arcade game built with Phaser 3 — aim, shoot, and clear the balloons across increasing levels. This is an early demo and is still in active development, so expect rough edges and changing mechanics.

Learning resourcesReference projects I maintain to help developers prepare for Android interviews and to teach the architectural patterns that matter in production apps — Clean Architecture, MVI/MVVM, offline-first data flow, and Kotlin Multiplatform code sharing.
An offline-first list app sharing domain, data, and presentation state across Android and iOS, with native Compose and SwiftUI on top. Deliberately structured like a large codebase to demonstrate modularization, dependency boundaries, and architecture enforcement.
A compact offline-first Todo app built to rehearse the topics a Senior or Lead Android interview probes: Clean Architecture, MVVM, Room + Flow, Hilt, WorkManager, Compose, and testing. Each layer reads end-to-end in minutes, so the reasoning behind every decision stays discussable.
