Data & AI Engineer · Procter & Gamble
I build the automation, data pipelines and AI tooling behind order management and other organizations — and I'm the one who gets paged when they break.
I came into this through automation in 2023 and kept widening: first the workflows, then the platform that runs them, then the data they sit on, then the AI on top. What ties it together is that I stay responsible for things once they're in production — monitoring, incidents, root cause, the boring parts.
Most of what I build lives in a private enterprise repository, so this profile is coursework and side projects. The cards below are the real work.

How I use them: change data capture & incremental pipelines · medallion / golden-layer architecture · prompt and few-shot engineering · text-to-SQL grounding · semantic modelling & ontology governance · LLM accuracy evaluation · human-in-the-loop AI controls · observability and failure taxonomies · root-cause analysis · incident response · UAT & defect management · configuration-driven design · idempotent pipelines · PDCA
The opinion I'd defend hardest: knowing when not to use AI. If a problem can be solved reliably with rules and a well-maintained mapping, it belongs there — not in a language model. I've pulled lookup logic out of LLMs and into plain deterministic Python specifically to cut hallucination risk and keep decisions explainable. AI is for the reasoning. It shouldn't be doing your joins.
The other one: fix the class, not the symptom. When something breaks, the interesting question isn't "how do I make this case pass" — it's "what structural thing made this whole family of cases possible."
I'm neurodivergent, which I think explains some of that. A lot of attention to detail, and enough analytical persistence to keep pulling on a thread when something doesn't add up.
