At SmartQ, I build systems that process 200K+ daily transactions and 10M+ daily notifications, including a production RAG platform for 600K+ annual cafeteria-feedback records that reduced analyst triage effort by 60%.

Previously at Masters India and Crest Data Systems, I scaled API, billing, ingestion, and security telemetry platforms using Python, Go, FastAPI, Kafka, PostgreSQL, Redis, AWS, and GCP. I've improved critical-path throughput from 700 to 4,000 requests per minute, cut release cycle time by 60%, and led development of terabyte-scale security data integrations.
