Over the past year, I focused heavily on building and refining Summit, a SaaS crypto algorithmic trading platform with AI and neural network components, implementing UI features like hold-to-confirm and admin page headers. I also advanced j-uni-hid, a feature-rich USB HID firmware for ESP32-S3, adding event-driven capabilities and matrix support. In parallel, I worked on several secondary projects including a crypto model research tool, a poker computer vision system, a Windows file tagger (intag2), and various automation and utility tools like jolt (AutoHotKey alternative) and blackboard-launcher (E Ink note-taking launcher).
