  DevOps and Billing Engineer

  DevOps EngineerAt Spectranet Limited, I led a project to implement a comprehensive CI/CD pipeline using Azure Pipelines and Jenkins, streamlining the build, testing, and deployment processes. By setting up automated workflows and integrating various tools, I reduced build times by 40% and increased deployment reliability by 35%. This initiative not only improved overall development efficiency but also enabled quicker and more reliable delivery of new features and updates to users.In another significant project, I enhanced application observability and monitoring by implementing a robust solution using Prometheus and Grafana. This setup provided real-time insights into application performance and system health, including alerting and notification systems for prompt issue responses. As a result, downtime was reduced by 25%, and incident response times significantly improved, ensuring reliable and performant services for users.Billing EngineerAs a Billing Engineer, I managed and monitored end-to-end billing operations using Alepo BRM, overseeing pre-bill and post-bill processes. I played a crucial role in migrating our billing system to a cloud-based environment, re-hosting the application, modifying its architecture, and recoding functionalities to leverage cloud services. This migration improved scalability and performance, handling increased billing volumes and reducing processing times by 30%.Additionally, I ensured data integrity and standardization across billing operations. I participated in requirement meetings and data mapping sessions, recommending data standardization practices. By monitoring payment transactions and usage reconciliation, I identified discrepancies and implemented solutions for accuracy. Coordinating with third-party users and vendors on system integrations and process development streamlined operations and enhanced customer satisfaction, culminating in a 20% reduction in billing errors and a more efficient billing process overall.

  Lead DevOps | BlockChain Engineer

  Upgraded our blockchain infrastructure from Hyperledger Fabric to Hyperledger Besu, enhancing scalability and performance. Leading the migration, I redesigned the network architecture and configured nodes. This upgrade reduced transaction processing time by 40%, significantly improving system performance.Transitioned our deployment architecture from Windows Services to Kubernetes, using Helm as the package manager. This change simplified and streamlined deployments, reducing deployment times by 50% and improving application stability and scalability to meet user demands.Simplified our deployment process to enhance scalability and efficiency. By designing a standardized deployment pipeline with Jenkins and GitLab CI/CD, I automated the workflow from code commit to production. This reduced errors and deployment times by 50%, improving reliability and allowing rapid scaling.Optimized our database management using Liquibase for version control. This enabled us to track and apply database changes as code, reducing update times by 40% and improving deployment reliability. This optimization supported faster and more reliable development cycles. Show less
