What I'm looking for

I'm looking to build production-grade Android products and shared mobile architecture, with opportunities to improve developer tooling, automation, test coverage, and cross-application platform quality.

At DraftKings, I build shared Android modules used across casino, sportsbook, and lottery apps, while owning automation pipelines with Jenkins and n8n.

I built an internal test automation framework from the ground up and designed AI-powered developer tooling that improved test coverage and reduced regression cycle time.

Previously at myPOS, I delivered payment features for an Android app serving 500k+ users and led modernization of over half the codebase to Kotlin and Jetpack patterns. At Casualino, I migrated legacy Java to Kotlin and Jetpack Compose, created reusable SDK components, and integrated subscription billing that increased revenue reliability by 30%.

I also independently built and published Waymotion for Android and iOS with Kotlin Multiplatform, Clean Architecture, Jetpack Compose, and subscription monetization.
