SDE2 @ Flipkart

## About

Sasirekha MSVL — SWE, Backend & Infrastructure I'm a backend engineer with 4 years at Flipkart building platform\-scale infrastructure on GCP\. My core work spans an analytics query optimization platform — where I used Apache ANTLR to parse and rewrite SQL expressions with 100% production accuracy, significantly cutting BigQuery slot consumption across hundreds of daily pipelines — and real\-time inventory systems using Kafka, gRPC, and Guava Cache that reduced inventory lag from tens of minutes to under 5 minutes\. I've built high\-throughput data pipelines \(30k\+ records/second via Pub/Sub and Hibernate\), multi\-channel communication infrastructure delivering ₹1\.32 Cr/year in cost savings, and owned zero\-incident Big Billion Days readiness including a critical production fix for BigQuery streaming insert failures\. I work across the full infrastructure stack — Kafka, Airflow, BigQuery, Terraform IaC, Kubernetes — and have a strong track record of debugging and resolving production reliability issues at scale\.
