About me

From the data layer
to the experience.

Portrait of Nishol Chetty
Nishol Chetty / Data architect

I work across the systems that keep organisations running and the software people use on top of them. That combination shapes how I think: start with the real problem, understand how a system behaves, then make the solution clear enough to use and maintain.

My work spans established databases and modern data platforms, alongside independent products I’m building.

Microsoft Fabric · Azure · SQL · MariaDB · PostgreSQL · MySQL · Db2 · MongoDB
