At Portonics Limited, I scale production infrastructure for MyRobi and MyCirkle across multi-cluster Kubernetes environments, sustaining high-throughput traffic while maintaining zero downtime. I also run GitOps and CI/CD workflows with Argo CD, Jenkins, Harbor, and Docker.
I maintain database high availability and disaster recovery across PostgreSQL/PGPool and Redis Sentinel clusters. I’ve also implemented observability and alerting, and automated recurring operational work with Python and Bash.
At Praava Health Bangladesh Limited, I built multi-cloud infrastructure as code across AWS and Azure using Terraform, and automated Node.js delivery pipelines with Jenkins. I embedded security checks into delivery and helped optimize Azure resources, generating $4,800 in annual recurring savings.
At Technohaven Company Limited, I developed CI/CD pipelines for diverse application stacks and disaster recovery workflows across DC, DR, and Far-DR sites. Before that, as a Network Engineer at Square Informatix Limited, I configured Cisco and MikroTik hardware and supported network, server, and infrastructure operations.
