Mobile craft

Production-ready Android and iOS delivery with maintainable architecture and polished UI.

Hardware-aware mobile

Strong experience bridging mobile UX with IoT communication, firmware data, and device control.

Delivery mindset

Performance tuning, CI/CD automation, mentoring, and shipping with maintainability in mind.

About

Engineering discipline with a product delivery mindset.

I am a mobile developer with 4+ years of experience designing and deploying Android and iOS applications using Kotlin, Jetpack Compose, and modern architectural patterns. I enjoy turning complex technical requirements into maintainable mobile systems that perform well in production and remain easy for teams to extend.

My work has spanned reactive interfaces, online-offline data flows, Firebase-backed mobile services, iOS feature delivery, and IoT communication using USB and LoRa. I am especially interested in solving problems where mobile software has to handle real-time device data reliably.

Mobile + IoT

IoT Device Control App

Designed Android interfaces for configuring and controlling connected devices through USB and LoRa communication paths.

Problem
Complex device interactions had to be translated into stable, understandable mobile workflows.
Approach
Used Kotlin, Compose, and clean state management to bridge device operations with reliable UI feedback.
Stack
Kotlin, Jetpack Compose, Coroutines, Flow, USB communication, LoRa protocols.
Data Flow

Real-Time Data Visualization

Built interfaces that presented live device or sensor data with responsive screens, local persistence, and resilient online-offline behavior.

Problem
Users needed real-time visibility without sacrificing app responsiveness or stability.
Approach
Combined reactive state flows, caching layers, and optimized API exchange formats.
Impact
Improved responsiveness and contributed to a 25% reduction in network latency.
Architecture

Mobile Stability and Delivery Modernization

Improved maintainability, crash resilience, and release quality through architecture, lifecycle cleanup, delivery automation, and stronger mobile engineering practices.

Problem
Growing mobile products needed stronger reliability and clearer separation of concerns.
Approach
Introduced cleaner module boundaries, repository layers, CI/CD workflows, and performance profiling.
Impact
Reduced ANRs by over 50% and improved release confidence through automated distribution.
