Umair A. Hassan — Senior Cloud Engineer

Introduction

About Me

I'm a Senior Cloud Engineer with deep expertise in Oracle Cloud Infrastructure (OCI), AWS, and GCP — building and operating enterprise-scale systems across all three major cloud platforms. My work centers on making complex, multi-cloud environments run faster, more reliably, and more cost-effectively.

At Oracle, I led infrastructure automation for Oracle Textura Payment Management (TPM) — a large-scale SaaS platform — driving significant improvements in deployment efficiency, system reliability, and security posture across multi-region OCI environments.

Across my career I've architected and managed cloud solutions on OCI, AWS, and GCP — from Kubernetes-orchestrated microservices and Terraform IaC, to cross-cloud IAM, CI/CD pipelines, and cost optimization strategies. I understand the nuances of each platform and know how to leverage the right tools across clouds to deliver the best outcome.

I also work directly with external clients — demoing new features, supporting onboarding, and translating complex multi-cloud architectures into real business value. I care deeply about building systems that are both technically sound and aligned with real business outcomes.
