What I do
Full‑stack engineer focused on Java/Spring backends, secure auth, and tidy UIs. I like strong typing, friendly DX, and observability you actually read.
Currently
Actively expanding Stella — my AI VTuber that speaks, moves, and remembers — to deepen contextual memory and multi‑platform presence (Discord ↔ Twitch). Also tightening backend observability and experimenting with OpenAI streaming for lower‑latency dialogue.
Fairview — Interview Anti‑Cheating Detection
Cross‑platform system monitor detecting cheating during technical interviews. Tracks processes, hardware configs, audio capture, and screen overlays with weighted risk scoring.
