At ARK Builders, I developed ARK Rate from scratch: a currency converter with portfolio support, published on Google Play. I also developed ARK Navigator, a file browser with advanced tagging and file indexing.
I migrated ARK Drop to Kotlin Multiplatform, moving its non-UI code into a shared module and adapting the Rust file-transfer library integration. I’ve also worked on other applications, developed reusable libraries, performed code reviews, and set up CI/CD pipelines with GitHub Actions.
On Upwork, I’ve completed more than 20 freelance projects involving feature implementation, performance optimization, refactoring, and ad integration. My reverse engineering work has included analyzing application logic and modifying APKs with Smali.
For personal projects, I published NetLens, an on-device network traffic analyzer, and Puzzle Chan, a puzzle game with AI-generated collectible images that reached 10,000+ downloads and a 4.0+ rating. I also developed VK SPY, which reached 5,000+ downloads.
