Rajeev Gill

I build practical software around AI, data, analytics, and adtech.

My work sits between product thinking and implementation, with a bias toward systems that make real work less messy.

Based in London. Interested in useful AI, clearer measurement, and software that holds up outside a demo.

The Projects Behind This Portfolio

A closer look at the public projects on rajeevg.com, what each one does, how each one works, and the stack choices behind them.

When Not To Use Server-Side Tagging

A real Cloud Run cost autopsy from rajeevg.com, with concrete guidance on when server-side tagging is overkill and when same-origin server-side tagging is actually worth the extra cost and complexity.

Have something useful to build?

I am always interested in thoughtful software, analytics, and AI work where the practical details matter.
