Experience

Senior Software Engineer

Aug 25 - Present

Designed, developed, and maintained OCI’s customer-facing realtime inter-region Network Performance Monitoring (NPM) solution, delivering minute-level round-trip time visibility across 150+ cloud regions in multiple isolated OCI realms.
Designed, implemented, and migrated the global network telemetry pipeline from PySpark to Kafka Streams, reducing costs from $20K to $10K/day while processing metrics at ~10Billion/min.
Extended the global network telemetry pipeline to ingest metrics from OCI's multiplanar network topology. The overall pipeline processes metrics at ~10Billion/min across ~100 regions, delivering metrics to customer monitoring systems in under 10 seconds.
Re-architected and migrated regional operations workloads from dedicated nodes to serverless Functions, eliminating host maintenance and reducing infra cost to ~$0.

Senior Software Developer

Architected and built a Data as a Service (DaaS) platform managing 10+ TB of data across the organization, cutting data-access turnaround time from 3 days to ~5min while maintaining SOC 2 compliance.
Led development of an in-house Unified Payments Interface (UPI) switch that processed 5M+ transactions daily.
Deployed a multi-region, on-premises Hardware Security Module (HSM) solution for UPI PIN management, supporting 10M+ queries daily while ensuring high availability and disaster recovery.
Built a memory-efficient UPI virtual payment address (VPA) blacklist with a Bloom-Filter, reducing unauthorized VPA assignments to strengthen fraud prevention.
Built the Sanction Screening Service end to end, enabling checks against 100+ global sanctions lists to reduce regulatory/compliance risk.
Built the initial Avatar service to generate personalized profile avatars from user selfies in real time.
Reduced risk-assessment latency 10x, from 20 seconds to under 2 seconds, across 100+ decision factors.
Designed and deployed an AWS Lambda-based NameMatch service to compare names across sources, detect fraudulent patterns, and resolve cross-service inconsistencies, reducing customer onboarding errors by 10%.
Integrated Sentry, APM, and VictoriaMetrics across multiple services, improving MTTR for production incidents.
