About

I’m a Senior Mobile Engineer with over 15 years of experience crafting scalable, high-performance apps across finance, healthcare, education, streaming, and more. I’m passionate about clean architecture, automated testing, and delivering measurable business value. I’ve contributed to apps used by millions of users and collaborated with teams around the world, leveraging Flutter, Swift, Kotlin, and MVVM patterns to ship delightful experiences.

In leadership and cross-functional roles, I mentor developers, drive AI-assisted development, and advocate for CI/CD, VIPER/Clean Architecture, and robust testing. I enjoy turning complex ideas into solid, maintainable mobile solutions and continuously exploring new technologies to accelerate delivery and impact.
