Architectural depth on a Kotlin Multiplatform codebase built from the ground up — a non-custodial digital wallet with 100K+ installs, where security and privacy constrain every structural decision across Android, iOS and JVM. Primary Android developer and architecture contributor, engaged to raise the team's architectural bar across the platform.

Led a mobile team of 10 engineers (5 Android, 5 iOS) plus design — sprint planning, delegation and alignment across backend, product and support. Led the mobile side of Computer, DevRev's conversational AI teammate — architected how the app consumed the AI backend, built features hands-on, and shipped it to customers.

Solely responsible for every structural decision in the app's first year: Clean Architecture, an MVVM/MVI hybrid, the repository–use-case pattern, and a KMP foundation the whole team later built on.

As the mobile org scaled to ~45 developers and split into three sections (Home, Work, Small Business), led the Small Business section on a consumer app with 500K+ Android installs, serving clients globally. Drove Clean Architecture adoption and early Kotlin Multiplatform to share the domain layer between iOS and Android.

Joined working across both iOS and Android, establishing shared architecture patterns and contributing to early KMP integration.

Independent Android contractor — grew from junior to senior across multiple product teams, and contributed to an accessibility app for blind and visually impaired users with the University of Ljubljana (Visual Assistant, 2016).

Built the Android app alongside iOS and grew the team to four.

Pivoted to modern Kotlin and multi-module structure — a turning point in architectural thinking.

First professional role, at an agency delivering MVPs for YC-backed startups — broad SDK exposure across many product domains.

Contributed to an accessibility app for blind and visually impaired users (Visual Assistant, 2016).
