About Me

I am a Mobile Engineer based in Tashkent, Uzbekistan with over 5 years of hands-on experience building production mobile apps across fintech, digital banking, e-commerce, and ad-tech.

I work primarily in Kotlin and Jetpack Compose, with multi-module architecture (MVVM / MVI), type-safe Jetpack Navigation, and dependency injection (Koin / Hilt). I also build cross-platform with Kotlin Multiplatform and Compose Multiplatform, and have shipped Android and iOS SDKs consumed by Flutter and React Native apps.

I own features end-to-end — from architecture and UI through unit / UI testing, CI/CD, and release to Google Play. I have shipped apps with 100K+ downloads and led large-scale redesigns and architecture migrations inside production banking apps.

I also build AI-assisted development workflows with Claude Code — custom skills, multi-agent code review and automated quality gates that run on every push.

Currently working as an Android Developer at Mikrokreditbank, where I led the full redesign of the Mavrid app and its migration from XML views to Jetpack Compose and a multi-module architecture, built the bank's Compose design-system library, and shipped the Kotlin Multiplatform Mavrid Kids app.

Work Experience

Android Developer

Mikrokreditbank · Commercial bank

Dec 2025 — Present
  • Led a full redesign of the Mavrid app, migrating the codebase from XML views to Jetpack Compose
  • Migrated the app from a monolithic structure to a multi-module architecture, improving build times and separation of concerns
  • App user base grew by 130,000+ within six months of the redesign
  • Grew unit-test coverage to 400+ test files (~130K lines) across feature modules to stabilize core flows and catch regressions early
  • Set up CI/CD pipelines to automate builds, testing, and releases
  • AI-assisted engineering: introduced Claude Code as the daily coding agent, governed by project rules I authored (CLAUDE.md + working agreements): phased plans, mandatory compile/test verification, and Clean Architecture / module-isolation guardrails
  • Custom AI workflows: built 10 Claude Code skills that automate recurring work end to end — backend v4 API migration, multi-agent code review with 5–10 parallel reviewers and adversarial verification, review-fix, unit-test generation, GitLab MR inline review, APK builds and branch sync
  • AI quality gate: added a pre-push hook that runs unit tests for changed modules, enforces Clean Architecture layer rules, and has Claude review the Kotlin diff — blocking pushes on real bugs, threading mistakes and leaks
  • AI-maintained documentation: kept ~50 per-module technical docs, a testing guide and an API-migration guide in sync with the code, used as context by both developers and AI agents
  • MKB UI Core: built the bank's Jetpack Compose design-system library from scratch in ~2 months — 15 components, 165 icons, multi-brand light/dark design tokens, 87 Roborazzi screenshot tests, explicit-API surface, and GitLab CI publishing to a private Maven registry; consumed by 4 apps
  • Mavrid Kids: built a Kotlin Multiplatform children's banking app (shared ViewModels and logic for Android & iOS, 28 modules, ~22K LOC, 270 unit tests) in ~2 weeks with an AI-first workflow: Figma-to-code skill, ~10-agent parallel code review with a verifier agent, and on-device verification over adb

Android Developer (Part-time)

Orient Advertisement LLC · Digital signage / Ad-tech

May 2026 — Sep 2026
  • Built a native Android TV-box digital-signage player running on 3,000+ devices across Korzinka stores, all airports in Uzbekistan and city billboards
  • Synchronized playback: screens switch content on a server-anchored shared clock, with upcoming media prefetched and swapped in at the scheduled time
  • Offline-first sync: WebSocket push with polling fallback, resumable downloads (HTTP Range), staged playlist swaps, storage checks and per-file download-state reporting
  • Remote fleet management: real-time command channel (reboot, volume, playback, content assignment, diagnostics) with cross-channel deduplication and a persistent confirmation queue, plus live remote screen sessions
  • Kiosk & resilience: Device Owner lockdown, crash recovery, boot autostart, a foreground service for playback and control, and heartbeat telemetry for unattended devices
  • Quality & AI: ~695 unit tests (~14.5K lines); built with Claude Code using custom skills for task intake, on-device smoke tests and backend-contract conformance checks
