Project: ORImperium – Network Data Reconciliation Platform Key Contributions in ORImperium: Testing & Collaboration: Project: GTCJ – Generic Test Java Controller

• Client: British Telecom (Openreach)
  Duration: July 2021 – Present
  Projects: ORImperium, Netviz, GTCJ
• Worked on a critical telecom reconciliation platform to compare and align data across Inventory (SRIMS), EMS systems (Nokia, Huawei, Adtran), and SABOR (Oxygen).
• Implemented logic to identify discrepancies and enable EMS-level write operations like ONT creation/deletion, Multicast, and GEA provisioning based on real-time validations.
• Developed complex workflows using Camunda BPMN for request processing and data transformation.
• Led end-to-end development across:
  Backend: Java, Spring Boot microservices
  Frontend: Angular, JavaScript, Node.js
• Built and enhanced microservices in Netviz to:
  Communicate with UI and Imperium
  Convert and format Imperium data for the UI
  Directly integrate with Adtran EMS for device operations
• Delivered Huawei Delete Functionality with highest complexity (5/5):
  Implemented ONT, Multicast, GEA delete flows with automation (ConfigONT + ApplyService)
  Integrated ONTSTATUSCHECK API
  Modified 15plus BPMN flows and created 1 new flow
  Contributed to full-stack changes across UI, Netviz, and Imperium
• CI/CD Implementation:
  Set up CI/CD pipelines for UI, Netviz, Imperium across lower and higher environments using CloudBees Jenkins, GitLab, Nexus, SonarQube, Ansible
  Automated deployments using shell scripts and Jenkins YAML pipelines
  Reduced production deployment time from 30 mins/site to 5 mins/site
• Database Migration Automation:
  Implemented Liquibase for version-controlled PostgreSQL database changes
• Developed new Adtran features:
  Integrated Serial Number Search API and Interface API
  Enhanced device search functionality in Adtran flows
• Participated in Unit Testing, Integration Testing, Regression, and Sanity Testing
• Collaborated with cross-functional teams: designers, developers, DevOps, QA, and business leads
• Worked in both Agile and non-Agile environments
• Developed diagnostic tools for telecom networks integrating with systems like SMARTS (alarms), SRIMS (inventory), NIA (network intelligence), and Imperium
• Delivered stories like:
  Identifying wrong ports in Huawei configurations
  Integrating new Nokia API to fetch serial number and model type
• Contributed to diagnostics logic, API integrations, and microservice enhancements
• Actively participated in testing, collaboration, and agile ceremonies
