Data & AI systems that make it to production.
I'm Rishi Bhatia, a data & AI strategist and engineer in San Francisco. For the last decade I've turned research models, raw telemetry, and empty infrastructure into systems teams rely on every day.

After a decade building AI and data systems at scale, I've learned that better operations don't come from more tools — they come from owning your data model. When my laptop is closed I'm strength training, swimming, snowboarding, or deep in a 1:1 café conversation somewhere in SF.
I take on a small number of engagements alongside running Ceroh:
-
Build sprints
Scoped 30-day builds of data platforms, pipelines, and AI workflows, run through Ceroh — inside your own infrastructure, handed off so your team owns it.
-
Fractional data & AI leadership
An experienced head of data for teams not ready to hire one full-time: architecture, vendor decisions, hiring, and the first builds.
-
Advisory
A second pair of eyes on your data model, your stack decisions, or an AI roadmap that needs grounding in production reality.
Working on a hard data or AI problem?
Email is the fastest way to reach me, or grab time directly on my calendar. I'm always glad to compare notes — or to meet for a coffee in San Francisco.
