Building voice AI in production
Software Engineering Intern
March 2026 — August 2026 Bengaluru
- Worked directly with the CTO in a fast-paced startup team, using Agile/Scrum practices and Jira to plan and deliver product work.
- Built and deployed production LiveKit workers for concurrent inbound and outbound voice calls, with lifecycle management, failure recovery, and horizontal scaling.
- Implemented secure BYOK infrastructure that routes LLM, speech-to-text, and text-to-speech requests to each tenant’s configured providers.
- Engineered agent-to-human transfers across LiveKit, Asterisk, and PSTN with retry, timeout, emergency escalation, and call-context preservation.
- Integrated Twilio and Interakt for WhatsApp plus Telnyx for SIP and voice through a shared provider abstraction.
- Built crash-resilient per-call diagnostics with incremental S3 multipart streaming, secret redaction, and a zero-loss JSONL fallback.
- Shipped natural-language callback scheduling with notice windows and duplicate-call protection directly into the existing campaign scheduler.
