DevOps Engineer
Technology Revolutions Inc
November 2022 - March 2024
- - Established and automated Jenkins based CI/CD pipelines and Terraform deployments to reduce infrastructure costs by 30% while achieving 28% faster deployments with minimized errors. Optimized security incident response by 20% through improved monitoring with Prometheus. - Led the implementation of Kubernetes autoscaling and namespace-based security policies for Northern Trust Corporation's EKS clusters, resulting in a 25% reduction in infrastructure costs, 15% increase in application performance & significant increase in security compliance. - Led the orchestration of a robust data pipeline using Filebeat and Kafka, achieving a 50% reduction in log processing time for Kubernetes pods (EKS) and seamless delivery to AWS Security Hub, thereby streamlining security posture management. - Designed and harnessed a highly available (HA) architecture for mission-critical applications in the financial services industry with statefulsets, deployments, and services for pod management and load balancing with automated failover mechanisms, ensuring near 99.99% system uptime. - Secured Terraform state using S3 and DynamoDB for fine-grained access control.
Technical Programs Manager (SW & Cloud Infra)
GenXComm Inc
August 2021 - September 2022
- Promoted and drove a DevOps culture, reducing deployment times from monthly to weekly (30% increase in frequency) & streamlining CI/CD pipelines. Partnered with Product to prioritize resilience, achieving a 15% reduction in post-release incidents. - Streamlined EKS deployment processes by implementing GitOps workflows with ArgoCD, enabling faster, more reliable deployments and simplified rollbacks. Spearheaded incident response process improvement, leading to a 20% reduction in resolution time and minimized downtime through proactive log analysis and troubleshooting with Prometheus & Grafana dashboards. - Built data pipelines for IoT based applications to ensure batch processing of sensor data using S3, EMR and DynamoDB. Upgraded the functioning of the data pipeline by triggering it using EventBridge and Lambda. - Built a scalable 5G Network Management System entirely on AWS, using CodePipeline, VPC, S3, CloudFront, ECR, EKS, Kafka, and MQTT. - Developed reusable Terraform modules for consistent infrastructure components, promoting maintainability and scalability.
