Senior Software Engineer

Aug 25 - Present

Designed, developed, and maintained OCI’s customer-facing 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.
Extended the global network telemetry pipeline to ingest metrics from OCI's multiplanar network topology. The overall pipeline processes ~10 billion metrics per minute across ~100 regions, delivering metrics to customer monitoring systems in under 10 seconds.
Re-architected and migrated regional operations workloads from dedicated hosts to serverless infrastructure, eliminating host maintenance and reducing infrastructure costs.

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 under 5 minutes 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, ensuring high availability and disaster recovery.
Built a memory-efficient UPI virtual payment address (VPA) blacklist with a Bloom filter to strengthen fraud prevention.
Built the Sanction Screening Service end to end, enabling checks against 100+ global sanctions lists to prevent fraud.
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 to improve monitoring and diagnostics.
