About me
Senior Android Developer with 10+ years of experience building high-performance, scalable Android apps. Expert in Kotlin, Jetpack Compose, Clean Architecture, and Coroutines. I've led end-to-end mobile development lifecycles, achieving 99.9% crash-free sessions and 25% faster load times in production. Recently built an AI-powered e-commerce Android app integrating OpenAI image generation and intelligent UX flows. I mentor developers, optimize CI/CD pipelines, and deliver modular, testable codebases. Open to freelance Android projects — from architecture consulting to full app development.
