I take AI from whiteboard to regulated production, and I know what it costs to run.

I'm an AI engineer & solutions architect. Ex-Google, ex-AWS (11× certified), most recently leading GPU-PaaS and distributed-LLM infrastructure at Rafay. I advise, architect, deploy end-to-end, and operate cost-optimized production AI, at founding / fractional-CTO altitude.

A document-understanding platform for a regulated Malaysian bank

Designed, built, and shipped an AI document-understanding platform inside a regulated, data-resident, human-in-the-loop environment, where the model is the easy part and everything around it (residency, auditability, a human who can always say no) is the hard part.

how I work

01

End-to-end ownership

Whiteboard to production to handover. The measure is whether the client can run it after I leave.

02

Cost is a design constraint

I track what every system costs to run, and optimize it. I do it for my own portfolio too.

03

Human-in-the-loop AI

In regulated settings the human is the control, not the inefficiency. Confidence-gated, auditable.
