What I'm looking for

I’m looking for a product-focused team where I can own end-to-end delivery—system design, API architecture, and cross-platform mobile performance—while improving release quality with CI/CD, automated testing, and modern React Native/TypeScript practices.

I’m a senior full-stack mobile engineer with 12+ years designing, developing, and deploying scalable cross-platform apps across web, iOS, and Android ecosystems. I’m highly proficient in React, React Native, and TypeScript, and I build performance-driven frontend architecture with modern state management and clean API integration.

I own end-to-end product delivery—from system design and API architecture to cloud integration and CI/CD automation—building reliable mobile releases through App Store and Play Store workflows. I also strengthen the stack with backend development in Node.js and Python (RESTful + GraphQL), native iOS/Android interoperability (Swift/Kotlin), and automated testing to improve stability and release quality. I’ve led React Native migrations, modernized Expo/EAS release pipelines, and used AI-assisted coding tools to accelerate development and refactoring.
