At Datanimbus Technologies, I lead cloud and platform initiatives while coaching a team of five DevOps and Platform Engineers. I stay hands-on with technical direction, architecture guidance, design reviews, and delivery.

I modernized critical payment APIs in Go, improving performance by 40% with backward compatibility and zero-downtime deployments. I also built a configurable rule engine for cross-border payments that made 60–70% of business logic configuration-driven and accelerated feature rollout by 80%.

I’ve created reusable multi-region cloud, CI/CD, and Infrastructure-as-Code capabilities with Terraform, Jenkins, Ansible, and ArgoCD, cutting manual intervention by 90%. My AWS and Kubernetes/OpenShift modernization reduced new-region deployment time from three weeks to one day and cloud costs by 45%.

Earlier, I built B2B and FinTech platforms at Medikabazaar, IDfy, and Capiot Software, working across Go, Node.js, Java, Elixir, PostgreSQL, and MongoDB. I also published an open-source Terraform module for standardized AWS IAM provisioning.
