Supporting and maintaining apps with 100k+ downloads.

Mobile developer since 2023, supporting and evolving production apps with Kotlin and Java, Jetpack Compose, and architectures that scale. Advanced Android pentest apps and build tooling to fix the findings. I care about the details: UI fluidity, tests that catch regressions before release, and code the next dev can read without crying.
