BangladeshFreelance DevOps & Full-Stack Engineer at Fiverr / Independent Clients

About

At MyMedicalHub International Limited, I ran the Azure platform behind a 10-microservice healthcare product on AKS, VMSS, App Service, and Docker. I built a Prometheus, Grafana, Loki, Promtail, and Alertmanager observability stack that cut incident debugging time by 80%. I right-sized VMSS and AKS node pools, reducing monthly compute spend by 21–36% without availability loss during traffic spikes. I also provisioned infrastructure with Terraform and Azure Bicep and set up Git-based CI/CD. At JoinAffix Private Limited, I designed and ran AWS infrastructure for 20+ production applications as the sole engineer at an early-stage startup. I replaced manual releases with GitHub Actions pipelines and built and shipped applications for healthcare, e-commerce, and AI clients. As a freelance engineer, I maintain 99.9% uptime on client workloads across AWS, Azure, and DigitalOcean. My projects include EKS observability and GitOps delivery, plus an internal developer platform using Go, Helm, and Flux.
