Lab as a Service/Resource Manager

• Implemented backend changes to support Hierarchy View of devices. Technologies used: Golang, Postgres DB
• Implemented recursive CTE SQL query to compute ancestors and descendants for a given device. Technologies used: Golang, PostgresDB, Squirrel
• Reduced performance tests runtime by 83% Technologies used: JavaScript, k6
• Enhanced bash script for trimming Redis streams to compute list of Redis streams instead of using hard coded list from configuration. Technologies used: BASH, Redis

Cross Domain Automation

• Built MCP tools using Langgraph, Langchain, and Model Context Protocol in Python to query Cisco’s action orchestrator service for workflow data.
• Helped develop and test Workflows MCP Server that hosted tools to query Action Orchestrator.
• Integrated these tools with Meraki’s Neo AI assistant by embedding them into Neo’s agent graph, while Neo handled agent orchestration and routing logic.
• Wrote Dockerfile and Kubernetes Helm chart to deploy the MCP server to Meraki’s local dev and production clusters

• Designed and implemented Virtual Network Router (Logical Router) Custom Resource controller, unit tests, E2E tests for CN2 - Cloud Native Contrail Networking system. Technologies: Go, Go-Kubernetes-API, Kubernetes, ETCD, Docker, Ginkgo
• Designed and implemented Kubernetes controllers, unit tests, and end-to-end tests for Port Mirroring in the Cloud Native Contrail Networking project. Technologies: Go, Go-Kubernetes-API, Kubernetes, ETCD, Docker, Ginkgo
• Discovered bugs by developing a SOAK Testing Automation system simulating production environments. Technologies: Python, Paramiko, GEvent, Jenkins
• Implemented logging module enhancements, improving API server memory usage. Technologies: Python, Docker
• Resolved customer escalations (AT&T, Orange) by writing scripts to heal customer environments. Technologies: Python, Cassandra DB, Zookeeper, RabbitMQ
• Led Juniper Intern Event, "Internet Day," organizing educational games for East Palo Alto elementary schools.
• Reduced ticket resolution time by developing a database management tool for resolving Zookeeper and Cassandra inconsistencies using a BFS-based tree format. Technologies: Python, Cassandra DB, Zookeeper
