About Hasan Butt
SYSTEMS ENGINEER // MLOPS // SRE PLATFORMS // FINOPS
I'm Hasan. I do three things, and I do them for real production systems — not demos.
First, I keep things running.
I build Kubernetes platforms on EKS, design SLOs that engineers actually respect, and set up incident response so that when things break at 3am — and they will — the fix takes minutes, not hours. Reliability isn't a dashboard. It's a system of decisions made before the outage.
Second, I cut cloud costs.
Most AWS and GCP bills are 30–50% waste: idle compute nobody remembers launching, storage nobody reads, and egress nobody planned for. I find it, kill it, and set up guardrails so it stays dead. This work pays for itself in the first month, usually several times over.
Third, I run AI infrastructure.
Companies are burning money on per-token API pricing when a well-run vLLM deployment on the right GPUs does the job for a fraction of the cost. I build and operate self-hosted LLM serving and production RAG pipelines — with monitoring, evals, and cost tracking, because AI infra is still infra.
These three things sound separate. They're not. Reliability, cost, and AI workloads are the same problem viewed from three angles: run compute well.
Most teams have someone for one of these. Very few have someone for all three.
That's the gap I fill.
