About Hasan Butt

SYSTEMS ENGINEER // MLOPS // SRE PLATFORMS // FINOPS

I'm Hasan, an SRE and platform engineer based in Pakistan. I work with teams running cloud services and AI applications.

First, I keep things running.

I build Kubernetes platforms on EKS and work on service targets, alerts, and incident runbooks. My project notes describe the failures I investigated and the configuration changes that followed.

Second, I cut cloud costs.

I review compute allocation, storage retention, and network routes against actual usage. The aim is to reduce costs while keeping the capacity and recovery options the service needs.

Third, I run AI infrastructure.

I build model-serving and retrieval pipelines, including self-hosted GPU deployments. I compare quality, latency, and operating costs before recommending a change from a managed API.

These areas overlap in day-to-day work. A capacity decision affects both the invoice and the way a service behaves during a failure.

The case studies below and on the projects page explain my role, the constraints, and what changed.
