AI for finance, by someone who actually closes the books.

Most AI tools for finance are built by engineers who've never sat through a month-end. I'm a Chartered Accountant and Finance Controller building the tools I'd actually use myself — open-source, synthetic-data demos, written up end to end.

About


Domain depth — IND-AS, GST, audit, transfer pricing, ERP migrations — is common in Indian finance. AI literacy is becoming common in software. The intersection (controllers who can ship) is genuinely scarce. This site documents the next six months of building public proof: six projects, all open-source, all built on synthetic data, all written up end to end. New entries land roughly every fortnight; the newsletter carries the build log.

Portfolio in flight


Six projects over six months, ~10 hours a week, public demos and write-ups. Each ships as a deployed page, a GitHub repo, and a newsletter issue.
