I work on practical uses for AI at Corsair. I spend time with teams learning how they work, figure out where AI could help, and build internal tools around what they need.

A lot of that starts with understanding the process people already have. The aim is to give individuals and teams time back by automating work that can reasonably be automated. I also research newer technology and explore how we could use it within the company.

Outside work, I build projects that interest me. Right now, those include an open-source iCUE companion app for controlling RGB lighting from a phone, and experiments with phone agents.

iCUE companion app

An open-source app that lets you control your RGB lighting from your phone. Phone control is working, and I’m making improvements as I explore more of the iCUE SDK.

AI cluster at Computex

Four AI300 workstations running local models. I set up the infrastructure and built the workflow for a demo comparing local models with paid AI services.

An ongoing project exploring agents that make calls about appointments, with instructions and booking permissions reviewed before each call.
