Software Engineer / Software Architect · Founder
Denver, CO · Remote-first · TypeScript · React · Node.js · Go · Rust · Flutter
Senior engineer and architect with 10+ years and 150+ projects across SaaS, internal systems, cloud, logistics, eCommerce and AI-enabled workflows. I turn complex requirements and legacy platforms into secure APIs, clear specs and shippable roadmaps.
Right now I'm building Karnelian (a kernel for AI agents), RamQuest in Unreal Engine 5 and Fable Shrine on Roblox, while running engineering at Wurla and Kordspace.
