Work History
Network Domain Specialist
TELSTRA
11.2023 - Current
- Developed closed-loop assurance frameworks by correlating NSO service lifecycle events with Grafana alerts, Elastic logs, and network telemetry, enabling proactive detection and automated remediation of service degradations.
- Implemented real-time observability pipelines by feeding NSO telemetry, commit histories, and transaction logs into Grafana, Elasticsearch, Logstash, and Kibana, providing visibility into deployment health, API latency, and configuration rollback behaviours.
- Collaborated across DevOps, Network Engineering, and Observability squads to integrate NSO service orchestration with CI/CD workflows (Jenkins, GitHub Actions), ServiceNow change management, automated rollback logic, and version-controlled service models.
- Led cross-functional teams to implement strategic domain initiatives, enhancing service delivery.
SENIOR NETWORK ENGINEER (PROJECT: JIO)
TECH MAHINDRA
03.2021 - 12.2022
- Designed, deployed, and managed 5G Core microservices (AMF, SMF, UPF, AUSF, NRF, etc.) using Docker containers and Kubernetes Pods, ensuring high availability, scalability, and efficient resource utilization.
- Implemented cloud-native orchestration patterns using Kubernetes Deployments, StatefulSets, ConfigMaps, Secrets, Ingress, and NetworkPolicies, enabling secure, reliable, and production-ready 5G Core workloads.
- Developed RESTful integrations for 5G Core services, enabling HTTP/2-based API communication, automated test execution, and inter-service flows across AMF, SMF, and AUSF.
- Automated infrastructure using Ansible, reducing manual configuration time.
- Integrated observability tools such as Prometheus, Grafana, New Relic, and Splunk to monitor pod health, network KPIs, HTTP flows, and custom 5G Core metrics; configured alerts for latency, throughput, and node exhaustion scenarios.
- Built and maintained end-to-end CI/CD pipelines using GitHub, Jenkins, and container registries, supporting automated image builds, linting, unit tests, rolling upgrades, and blue-green deployments for 5G microservices.
- Conducted SIP/DIAMETER/LTE NAS packet analysis using Wireshark and Spirent Landslide logs to troubleshoot call failures, registration issues, attach/detach scenarios, and QoS mismatches.
NETWORK ENGINEER (PROJECT - AT&T)
TEAMLEASE - DXC TECHNOLOGY
06.2020 - 02.2021
- Conducted load, registration, and session stability testing using Spirent Landslide, validating real-time behavior of 5G Core microservices during scale-out, failover, and performance edge cases.
- Executed functional, regression, and performance testing on VoLTE, SRVCC, emergency calling (000), supplementary services, and roaming scenarios.
- Collaborated with cross-functional teams to define cloud-native architecture for 5G SA Core, ensuring high availability, resiliency, and compliance with 3GPP standards.
- Implemented Horizontal Pod Autoscaling (HPA) strategies using CPU, memory, and custom Prometheus metrics to optimize resource allocation for high-volume 5G sessions.
- Troubleshoot 5G network microservices using kubectl, container logs, pod events, and distributed tracing (Jaeger OpenTelemetry), reducing MTTR across network functions.
- Used Helm charts to package and version network functions, simplifying deployment, rollback, multienvironment configuration, and GitOps integration.
