API Development: Designed, developed, and deployed APIs built in Python (Flask) or Java (Spring Boot), integrated with database systems like MySQL (relational) or Neo4j (graph-based) based on application requirements and project constraints.• ADO (Azure DevOps) Pipelines: Developed numerous ADO Pipelines to automate various tasks, including CNOM user creation, ENS6 disablement, and changing mTLS mode in provisioning gateway YAML pod. Designed and implemented automated test cases for PFD (Packet Flow Descriptors), QOS (Quality of Service), and Provisioning Test Cases for NEF (5G Network Exposure Function), leveraging “curl” commands, YAML, Ansible, and Bash shell scripting. Achieved time savings of 32% per test cycle.• Security: Designed and implemented ADO pipelines for Hashicorp Automated Enrollment to securely fetch and retrieve SSH keys via KeyVault, ensuring data integrity and compliance with stringent security protocols.• Centralized Reporting/Dashboards: Generated centralized email reports with HTML body and attachments (.zip containing the detailed health check report per zone), using Python, Jinja2, and the mutt library. This automation initiative is saving 2-4 man-hours daily.• Software Development (Scripting): Engineered various automation tools, including:(1) A Python script for comparing NEF configuration files pre- and post-maintenance, highlighting differences while masking sensitive data, and (2) A comprehensive tcpdump shell script for real-time tcpdump trace enablement, monitoring process information, pcap data collection and processing, and efficient file management, including automated cleanup.• Docker and Kubernetes Exposure: Nearly 3 years maintaining and operating a containerized network function (NEF) based on Docker and Kubernetes, performing CCD and CCES layer upgrades, Helm upgrades, and deploying/troubleshooting pods, containers, replicas, PVC, volumes, and connectivity issues.
