Personal site — New York City

Ketu Shah

I build the customer data systems companies run on. I photograph New York City on foot as @walkwaywanderer. And I travel the same way: slowly, on foot, off the itinerary.

Work

Customer data, treated like infrastructure.

I turn customer data into something a company can actually use. Most companies collect more data than they can trust. I close that gap where it actually breaks: how data gets collected, how its quality gets enforced, and how it gets activated across marketing, personalization, product, and AI.

I’m an early adopter and a skeptic at the same time. I put new technology into production, and I stay skeptical enough to ask where it actually earns its keep. That’s the edge in a tech sector mired in one-sided thinking: hype on one side, dismissal on the other, and not much judgment in between.

Data quality. I build the layers that make data trustworthy: identity resolution that gives you one profile per person instead of one per system, governance that keeps collection clean at the source, and automated checks that catch breakage before anyone makes a decision on bad data. AI is only as good as what’s underneath it. I make sure what’s underneath it holds.

Collection. I design how customer data enters the building: one governed way to record events, identity attached automatically, personal data kept separate. When collection is an afterthought, every downstream team pays for it. I make it a standard, so personalization, ML, and analytics all start from truth instead of janitorial work.

Activation. Data nobody uses is shelfware. I build the audience systems and integrations that turn a customer data platform into something the whole company actually reaches for: self-serve, documented, and adopted because it’s the easiest path, not because someone mandated it.

Patterns others miss. Part of the job is seeing what the dashboards don’t say: the slow drift in data quality, the integration everyone assumed was working, the number that moved for the wrong reason. I go looking for the thing nobody’s checking.

Grounded decisions. I decide on evidence, not on who’s loudest or what’s fashionable. Vendor evaluations run across legal, marketing, data science, and product, and they land because the criteria were honest. I set multi-year direction the same way: write down the reasoning, so the decision survives the meeting it was made in.

Process and culture, early. Systems break, but process and culture break first and quieter. I catch it early: the review bottleneck that’s really a trust problem, the tribal knowledge that’s really a documentation problem, the team waiting on one person for everything. Then I act on it. Automated checks instead of gatekeepers, standards instead of folklore, and people developed for autonomy rather than dependence.

The work spans technology, people, and culture, because in practice they’re the same job. Recent work includes a vendor-agnostic identity layer behind a Marketo-to-Iterable migration and an org-wide Tealium-to-Hightouch re-architecture, cut over product by product without disruption. The goal is the same every time: data the organization can trust, systems that run without me, and people ready to own what’s next.

Travel

The no-plan traveler.

I travel on foot and without an itinerary. Land somewhere, pick a direction, and let the day arrange itself around what you find. That is how you actually meet a place: not through the landmarks, but through the side streets, the corner shops, and the life happening in between.

Slow and unstructured, on purpose. I spend less time in curated museums and more time outside, where the city is still being itself. Nothing against museums; I would just rather spend those hours walking.

Walking is the obsession underneath all of it. I will cross a city on foot before I take a cab across it, and a hike is never the detour, it is the plan. The long way is usually the point.

Day trips run on the same logic. No bucket list, no must-see circuit. Get there early, walk until the place starts making sense, and leave the day unscheduled.

Writing

Notes.

Against the hype

I am not anti-AI. I use it every day. What I am against is the theater: the demo that never meets real data, the strategy deck that is really a press release.

Here is the unglamorous part nobody wants to fund. The AI is only as good as what is underneath it: clean identity, governed events, honest context. That work does not demo well, which is exactly why it gets skipped.

Use deterministic systems where you need predictability. Use probabilistic ones where judgment helps. Anyone with one answer for both is selling you something.

Don’t outsource your thinking

The problem with AI is not that it gets things wrong. It gets things wrong in perfect prose, confidently, and most people have stopped checking.

Critical thinking was already in decline before the models arrived. Now there is a machine that will do your reasoning for you and call it a day. Every time you accept its first answer, the muscle gets weaker.

Use the tools. Then argue with them. The moment you cannot explain why an answer is right, you do not know anything. You just have output.

What the new age asks of us

Every technology wave promises the same thing: thinking is now optional. It never is. The thinking just moves somewhere harder.

The people with leverage will be the ones who can tell signal from noise, who build systems instead of depending on them, who stay curious when the machine offers the easy answer.

That means judging the output, caring whether it is right, and taking responsibility for it. That has always been the work.

Press

Said out loud.

TODAY (NBC). “Why dinner parties with strangers are growing in popularity.” I was a guest at one of these stranger dinner parties, filmed for the segment. Watch.

Beyond the Screen (IONOS podcast). “The Uncanny Valley Phenomenon: The Impact of AI on Human Behavior.” Joe Nash and I talked about AI systems that mimic humans, how to spot fake AI-generated content by sweating the details, and what the technology means for society. Listen.
