At bKash, I operate six production EKS clusters supporting fintech workloads for 85M+ users, handling lifecycle management, incident response, capacity planning, and SLA-critical observability.
I've reduced AWS infrastructure spend by 20% through EC2 right-sizing, Spot adoption, Bottlerocket OS, and Savings Plans. I also modernized delivery from Jenkins to GitHub Actions, ArgoCD, and Atlantis, cutting deployment cycles from 30 minutes to about 10 minutes while eliminating secrets exposure across pipeline stages.
I build practical automation in Go, Python, Terraform, Ansible, and AWS Lambda, including a SlackOps platform used by 200+ engineers. I also taught Python and data structures at BRAC University and maintain yon, an open-source Go CLI for YAML and JSON configuration files.
