Voice AI team. Building and optimizing a high-concurrency Go telephony service powering Zomato's Voice AI — a real-time 4-stage pipeline (STT → VAD → LLM → TTS) with sub-second end-to-end latency under high-throughput production load. - Pseudo Turn End (core implementer): speculatively triggers LLM/STT processing on short VAD silence and cancels in-flight requests on misprediction. Cut per-turn latency by 800–900ms in production. - Resolved multiple critical production race conditions, including one in the call-termination flow causing premature call drops; refactored the teardown sequence to eliminate them. - Built an inline repetition-detection engine (sliding-window Jaccard similarity) that auto-terminates stuck calls, cutting wasted LLM tokens and STT/TTS API spend — zero false positives. - Established observability via structured event logging and Grafana/Redash dashboards across the VAD subsystem, enabling real-time tuning of speech-end thresholds. Tech: Go, gRPC, MySQL, Grafana, Redash, Docker, Python.

Engineering Productivity team. - Extended Kafka and OpenTelemetry instrumentation to propagate trace context via Kafka headers, enabling end-to-end distributed tracing across producer/consumer boundaries on a Git-based internal platform serving 800+ users. - Built a Go CLI (Cobra) and HTTP service for remote container diagnostics via docker-exec, replacing ad-hoc SSH-based debugging. - Deployed tracing agents as Kubernetes sidecars to validate trace continuity across a microservices architecture. Tech: Go, Kafka, OpenTelemetry, Kubernetes, Docker, Cobra.
