About Hasan Iqbal Butt
SYSTEMS ENGINEER // MLOPS // RAG INFRASTRUCTURE
I am Hasan Iqbal Butt (often known as Hasan Butt), a remote systems engineer specializing in bridging the gap between research machine learning models and high-uptime production systems. Over the past 6+ years, I have built, deployed, and scaled over 18 production systems across Amazon Web Services (AWS) and Google Cloud Platform (GCP).
My engineering approach is defined by strict metrics. I don't just deploy infrastructure—I configure it to measure performance continuously. Whether it is reducing a transformer model's cold start from 2 minutes to 8 seconds, cutting a client's AWS spend by $40K/year, or maintaining 99.9% production uptime, every architectural choice is backed by measurable telemetry.
As a Top Rated freelancer on Upwork with a 100% Job Success Score, I partner with fast-growing AI startups and established businesses to transition their prototypes into stable, compliant, and cost-efficient platforms. I design self-hosted GPU inference networks, deploy custom chunking and pre-filtering pipelines for RAG systems, and implement robust GitOps pipelines with OPA Gatekeeper verification to keep shipping schedules safe.
I am based in Lahore, Pakistan, and work remotely with engineering and leadership teams worldwide, aligning deployments with US, EU, and AU time zones.
