I built this project solo to combine conversational voice UX with structured interview assessment workflows, covering auth, data persistence, generation, and post-session scoring.

• > Implemented account flows with Firebase-backed signup/signin and secure session cookie handling for protected routes.
• > Added authenticated app layouts that gate interview and feedback routes based on session state.
• > Built interview question generation endpoint using Gemini with role, level, tech stack, and interview-type prompt inputs.
• > Integrated Vapi voice sessions for live mock interviews, with event-driven transcript capture and call lifecycle handling.
• > Implemented transcript-to-feedback pipeline using structured schema output for total score, category scores, strengths, and improvement areas.
• > Added feedback upsert logic so users can regenerate updated evaluations for the same interview.
• > Persisted interviews and feedback in Firestore collections with user linkage and created-at ordering.
• > Built dashboard views for user interview history and latest interviews from other users.
• > Added interview detail and feedback pages to review session context and actionable assessment output.
