About Me

Engineer. Author. Creative Technologist.

My path has taken me through many intersections of technology, creativity, and problem solving — from finance and media to cloud infrastructure, AI, and augmented reality.

I've worked in finance, media, AR, computer vision, cloud infrastructure, and tools for artists — always focused on building things that empower people to do their best work.

Today I channel that range into consulting, writing, teaching, and building at the intersection of software and human creativity.
