Engineering Lead · Staff Software Engineer at PlayStation

Engineering Lead with deep experience building end-to-end software systems — from frontend architecture and design systems to the backend services and APIs that power them. At PlayStation, I work across the full stack, designing and shipping production systems with a strong emphasis on performance, reliability, and long-term maintainability.

Beyond day-to-day engineering, I care deeply about growing engineers and raising the bar for frontend as a serious engineering discipline. I've mentored hundreds of developers and serve on the UC Irvine Customer Experience Program Advisory Board.

A clear, practical roadmap

This book is a clear, practical roadmap for anyone who wants to break into front-end development without feeling overwhelmed. Zero to Front End Hero explains concepts step by step, in plain language, and focuses on real skills you can actually use, not just theory. What stands out is how motivating it is. It makes learning feel achievable, even if you are starting from absolutely zero. The structure is logical, the examples are easy to follow, and the progression builds real confidence. This is the kind of guide that turns curiosity into action and action into competence. Highly recommended for beginners, career changers, and anyone who wants a solid foundation in front-end development.

One of the most practical property analysis tools for real estate investors

The app makes property analysis simple, organized, and efficient by bringing key numbers like rehab costs, ROI, cash flow, and projections into one easy-to-use workspace. … I especially like how practical the platform feels; it is clearly designed around real investor needs.

Super helpful for home investment insights

Instead of spending hours researching renovation costs or trying to figure out whether a property is a good investment, the app just asks a few simple questions and then gives you a full analysis. I like that it takes something that can feel overwhelming and makes it much easier to understand.
