Hi, I'm Sam.

I'm a Customer Engineer at Cloudflare in Austin. I work with companies across app security, Zero Trust, AI, and Cloudflare's developer platform, before the deal and after it.

Outside of work I build things. Most of that time goes into Reni AI, an iOS app I co-founded that turns a photo of your room into a renovation you can actually buy. More than 4,000 people have used it.

I studied computer science and data science at UW–Madison, and I'm happiest working on AI, sports data, and the simplest way to ship something.

When I'm not at a screen, I'm usually traveling or outside. Hiking is my favorite way to get to know a new place.

Reni AI · Co-founder

I built the AI backend. An intent classifier sends each request to the image model that handles it best (Gemini 3 Pro, Gemini 3.1 Flash, or GPT Image), with a Llama fallback on Workers AI through AI Gateway. Gemini Vision then finds the furniture in each render so people can shop it. 4,000+ users and $8,000+ in revenue so far.
