Saurabh Agarwal

Part of the core engineering team developing ColorTokens Spark (Xshield), a cloud-native, agentless security platform providing micro-segmentation, vulnerability detection, and continuous posture assessment for enterprise clients. Architected and implemented diagnostics collection, port metrics, sensor configurations and firewall coexistence pipelines in Golang, enabling secure and parallelized retrieval of system-level metadata across 10,000+ endpoints. Integrated and optimized telemetry data flow with Xshields core microservices, reducing diagnostics latency by ~35% and improving anomaly detection accuracy. Designed scalable RESTful APIs and gRPC-based services for agentless data collection, adhering to Zero Trust principles and multi-cloud compliance standards. Developed monitoring and alerting frameworks using New Relic and SonarQube, reducing MTTR by 40%. Collaborated with security intelligence and SRE teams to enhance observability pipelines across distributed Kubernetes clusters.

Owned the end-to-end design, development, and deployment of Golang-based microservices for the Billing team, leading improvements in scalability, resilience, and observability. Optimized billing deduction API, achieving a 90% reduction in response time through Golang concurrency and asynchronous I/O. Enhanced RabbitMQ throughput by 1,400% via Redis caching and batch processing. Doubled billing system throughput by profiling memory leaks and migrating to context-based logging and async metrics pipelines. Led monolith-to-microservices migration from PHP to Golang, reducing deployment times by 40%. Redesigned WhatsApp operational flows, cutting MySQL table dependencies by 66% and improving data integrity. Delivered features including Bulk Invoicing, Subaccounts, VMN Billing, WhatsApp Refunds, and Currency Exchange through cross-team collaboration and rigorous QA cycles.
