About

I am a software engineer with over 5 years of experience building and shipping iOS applications at scale. My work focuses on performance, architecture, and user experience, with experience delivering features end to end from concept to production. I am currently pursuing my Master’s in Computer Science at California State University, Sacramento. My primary expertise is in iOS development with Swift, and I have built features and products across e-commerce, fitness, and social platforms. I have worked on a range of mobile experiences, including ARKit, video calling, live streaming, and real-time chat. I have taken ownership of features across the full development lifecycle, from design and implementation to optimization and release. Alongside mobile development, I also explore applied AI systems, including retrieval and agent orchestration, which strengthens how I think about system design and product innovation.
