I design and ship complete systems — from ESP32 firmware and sensors, through backend services and Cloudflare tunnels, to the web and desktop interfaces on top. I like small, dependable tools that solve a real problem and just work.
Background: six granted U.S. patents on hybrid building networks (VUTP), NASA security consulting (contractor), and years of hands‐on IoT prototyping.
