About Me

I build full stack software and AI agents that solve real business problems. At Best Choice Products, I develop warehouse systems and tools for forecasting and pricing products. Outside of work, I explore everyday problems and build products that make people’s lives easier.

I graduated from UC San Diego with a degree in Mathematics-Computer Science. My experience spans full stack development, databases, cloud infrastructure, and AI systems, with a focus on bringing these pieces together to build useful products.

I developed my full stack skills through independent study, courses, personal projects, and internships at MyMicrojourney and Smart Twigs.
