Senior Android developer who modernizes Kotlin and Jetpack Compose apps, using AI-assisted workflows to ship faster.
What I'm looking for
I’m a Senior Android Developer with 10+ years building, modernizing, and scaling Android applications across e-commerce, mobility, ticketing, gambling, smart devices, and wearables. I focus on Kotlin and Jetpack Compose, using strong Android architecture practices, accessibility, testing, and production-grade engineering habits.
I’ve driven meaningful product improvements—like raising accessibility coverage from approximately 30% to 100% on a fashion marketplace app. I also helped transform a WebView-based mobile product into a mostly native Android experience, improving UX and maintainability, while collaborating closely with QA, backend, iOS, business, and product stakeholders.
In my current role at DataArt, I deliver Android features for large retail and booking/gambling flows and improve delivery reliability through code reviews and unit tests. I also apply AI-assisted development workflows for implementation planning, refactoring, bug investigation, unit test generation, and documentation—validating AI output with engineering judgment to preserve production quality and accelerate delivery by 5x–20x depending on the task.
