My professional journey in development and leadership roles

Software Engineer (Founder)

Mimir

April 2025 - Present

Mumbai, India

Built and shipped end-to-end real-time VoIP AI agents for customer support, architected multi-tenant versioning for scalability, and integrated advanced conversational AI features.

Key Achievements:

Built and shipped end-to-end real-time VoIP AI agents for customer support using FastAPI, WebRTC, LangChain, and OpenAI Realtime via Twilio Media Streams, cutting average handle time by 42% and improving first-contact resolution by 28% across 20+ SMB deployments.
Architected multi-tenant versioning with per-tenant vector stores and rate-isolated pipelines, enabling 5x concurrency scaling while maintaining sub-250 ms round-trip latency for speech-to-action loops.
Integrated Semantic VAD and intent-aware turn-taking to optimize barge-in and silence detection, reducing interruption errors and boosting CSAT by 18 points through more natural conversational flow.
Implemented telephonic RAG with tool-use for ticket lookups, order status, and booking flows, automating 65% of repetitive Tier-1 tasks delivering 1.3x ROI within 90 days.

Software Development Intern
