About Me

I'm wrapping up my Computer Science degree at SFSU, where I've built production-ready web apps, system integrations, and cloud deployments focusing on clean architecture and delightful user experiences.

From architecting a travel platform end-to-end on Azure to experimenting with OpenAI integrations and multimodal workflows, I love connecting design thinking with reliable engineering practices.
