Highlights

  • Built the realtime voice loop on OpenAI's GA Realtime API over WebRTC; debounced code-editor snapshots stream into the model so the AI reacts to what you type, not just what you say
  • Authored 15 structured per-problem 'interviewer briefs' (solution tree, 4-rung Socratic hint ladder, follow-ups, edge cases) that drive interviewer behavior via the system prompt
  • Layered cost protection: per-IP rate limit, 15-min session cap, ephemeral key TTL, and a Discord-webhook extended-access request flow with manual-whitelist approval
