About

Professional summary

I am a Staff Android Engineer with over 9 years of experience in software engineering and more than 5 years focused on modern Android architecture, including Jetpack Compose and Kotlin Multiplatform.

I have led high-impact mobile initiatives across fintech, telecom, e-commerce, and automotive products, building features that improved adoption, retention, performance, and reliability.

My background includes end-to-end ownership of Android architecture, cross-functional collaboration with backend and product teams, and delivery of scalable mobile experiences for large user bases.

I also work extensively with AI-enabled development workflows, using Claude Code and agent-based automation to improve code review, release validation, and testing efficiency.

I enjoy solving complex technical problems such as BLE connectivity, authentication redesign, streaming integrations, and mobile platform modernization.

I am open to opportunities where I can contribute as a senior individual contributor or technical leader in Android and mobile platform engineering.
