Member of Technical Staff - II (MTS-2)

ColorTokens Inc.
Aug, 2025 - Present 8 months
    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.
