I’m Ernest, a senior Unity & XR engineer and tech lead with a background in real-time simulation, architecture, and shipped games. I also design and ship full-stack products with .NET, Flutter, and cloud infrastructure.
A practical tool tracking app for construction teams. Scan tools, see who has them, and keep a photo-backed record of where they were left.
