Consulting · Arbab Chowdhury

AI automation and data systems, built pragmatically.

I wire up existing tools where they fit and build custom where it matters — and I tell you honestly which is which. Backed by 15+ years engineering regulated banking and healthcare data, so what I ship is correct, auditable, and doesn't break.

What I build

Outcomes, not hours. Most engagements are one of these.

RAG over your documents

Chat with your contracts, policies, and knowledge base — with source citations, so answers are grounded and checkable, not hallucinated.

AI workflow automation

Automations that run in the background — Make / n8n / Zapier wired to your tools, with AI where it earns its place. The repetitive work stops being your problem.

Data pipelines you can trust

Clean, validated, reliable movement of data between systems — with the reconciliation and correctness discipline of regulated financial reporting.

Build-vs-buy second opinion

Before you commit to a vendor or a custom build, a straight answer on which one you actually need — and a plan to get there.

Build vs. buy, done right

I don't sell custom code you don't need. To prove it, I built the same document-Q&A system three ways — no-code, managed-cloud, and custom — with an honest cost / control trade-off table. That's how I make the call on your project. See it on GitHub →

Regulated-data rigor

The differentiator most AI freelancers can't offer.

I sign BAAs, handle PHI and financial data to specification, and treat your data like the regulators are watching — because in banking and healthcare, they are. I've engineered compliance-grade data systems inside a top-10 U.S. bank and filed regulated healthcare data since 2017. Your sensitive project is in careful hands.

A 20-minute call is the fastest way to see if this is a fit.
