About Me
Current focus: Flutter, KMP, and AI-assisted mobile delivery
I’m a senior mobile application engineer with 5+ years of production experience across Flutter, Kotlin Multiplatform, Jetpack Compose, and SwiftUI. I have shipped 15+ apps across Google Play and the App Store with 200K+ installs.
I handle end-to-end delivery: architecture, REST/Firebase integrations, subscriptions, push notifications, deep links, testing, store submission, and post-launch maintenance. This helps clients reduce release risk and keep app quality stable as features scale.
I use AI tools (ChatGPT, Claude, Codex) to accelerate debugging and review cycles, while final technical decisions and production quality gates stay human-controlled.

AI Code Review How I Work
Senior mobile delivery is less about shipping fast in isolation and more about reducing ambiguity early, keeping execution visible, and taking responsibility through release.
Scope First
I align on platforms, user flows, backend dependencies, subscriptions, notifications, store constraints, and success criteria before implementation starts. That keeps timelines realistic and reduces avoidable rework.
AI-Augmented Delivery
I use ChatGPT, Codex, and Claude to accelerate debugging, diff review, implementation support, and edge-case exploration across Flutter, KMP, Jetpack Compose, and SwiftUI. Human review stays in every architecture and release-critical decision.
Visible Progress
Work moves in reviewable milestones with concise async updates, demoable builds, and early risk flags. Clients know what shipped, what needs review, what is blocked, and what comes next.
Release Ownership
I own the last mile: regression checks, release builds, store submission, rollout planning, Shorebird hotfixes, and post-launch stabilization. The target is a dependable release, not a handoff with loose ends.
