At Flexport, I served as Lead Engineer for the Outbound Logistics domain and architected a canary deployment framework for more than 100 microservices. I also developed the Automated Sorter launch pipeline at the EWR Warehouse, processing hardware packets and returning routing decisions within 50 milliseconds.

At Swiggy, I developed a geospatial notification framework for real-time customer alerts. Earlier, at Oracle, I built VBCS interfaces and Spring Boot REST APIs; at LibreOffice, I authored a native Calc data-provider interface for external data ingestion.
