Exotel

Jan 2025 - Nov 2025 Not specified
  • Engineered backend services for enterprise-scale cloud telephony on Linux, maintaining high availability for thousands of enterprise clients across production environments.
  • Built and tested REST APIs for telephony services via Postman; identified and resolved 15+ API inconsistencies across dev, staging, and production.
  • Wrote Node.js backend scripts for internal tooling and workflow automation, integrating with production APIs and distributed logging systems.
  • Designed an NLP-to-SQL Query Engine (Python, Flask, PostgreSQL) converting plain-English prompts to optimized SQL queries awarded the internal Medal of Honour; adopted company-wide by engineering and operations teams.
  • Built an Automated Webhook Retry System using Redis + exponential back-off, cutting missed-event support tickets by 65% and improving SLA for 200+ enterprise accounts.
  • Developed a Real-Time Call Quality Dashboard (Web Sockets, Redis Pub/Sub, Python) streaming live CDR metrics — reduced mean time to detect production call issues by 55%.
  • Automated monitoring workflows with Python scripting, reducing manual engineering overhead by 70%.
