I’m a software developer with a hybrid background across backend engineering, applied ML, and immersive XR experiences.

I enjoy building software that combines real-world data, interaction design, and AI to create meaningful tools and experiences — whether that’s clinical XR, computer vision pipelines, or lightweight local-LLM apps.

I studied international business, started my career in marketing, and then turned to software development and product, though I've been writing code since I was a kid. I’ve worked across many different functions, served on the board of a non-profit, and founded a VC-backed company, all of which makes me a well-rounded developer with broader skills than just dev.
