What I'm looking for

I seek frontend engineering roles where I can lead technical teams, build high-performance cross-platform products, and apply product-driven, business-minded engineering to drive user engagement and growth.

I am a frontend software engineer with a business background and a proven record delivering high-performance applications across entertainment, healthcare, finance, streaming, and gaming industries.

I lead technical teams and architect cross-platform solutions, including OTT apps and internal platforms, focusing on performance, scalability, and excellent user experience.

Notable achievements include building a Disney internal platform, refactoring a medical supplies mobile app to reduce bundle size by 30%, and optimizing banking and ecommerce applications to improve load times and conversion.
