InterviewEra

Apr 2026 - Present

Independently owned the full development lifecycle — architecture, implementation, testing, deployment, and ongoing maintenance — of a Next.js/TypeScript + Node.js/PostgreSQL production platform serving 250+ registered users. Engineered a real-time voice interview engine using WebSockets, Deepgram speech-to-text, and ElevenLabs text-to-speech, with adaptive LLM follow-ups conditioned on candidate resumes and prior answers and evaluated through a five-dimension scoring rubric. Implemented JWT-based authentication with Supabase Auth, Redis-backed caching and rate limiting, and a Razorpay credit-based payment flow for production usage. Shipped 100+ programmatic SEO pages via dynamic Next.js routes and structured metadata, generating 1.9K organic clicks and over 50k Google Search impressions with 3.6 CTR and an average position of 11 within 3 months.
