Built and maintained backend APIs for a high-throughput outbound calling platform (Java/Spring Boot) supporting predictive and manual dialing workflows. Implemented IVR system integrating RabbitMQ, FreeSWITCH, and async callbacks for reliable call outcome propagation. Contributed to an event-driven distributed system processing 10 lakh IVR calls/day, with focus on concurrency, fault tolerance, and scalability. Handled call lifecycle event processing on the frontend (Vue.js) to ensure consistent state sync across services.

Built microservices in Golang and Python (FastAPI, Celery, SQS) to fully automate QA scoring of customer support calls, achieving 100% automation and reducing manual QA effort by 70%. Implemented an event-driven architecture processing 6 lakh calls/day. Developed real-time agent productivity monitoring using SSE, Celery, and WhatsApp alerts to track idle time and break violations. Optimized frontend–backend interactions by centralizing API calls, cutting redundant requests by 50% and lowering API latency. Enforced API contract reliability via MyPy static typing and structured GenAI schema responses, reducing production issues.
