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.

Finding What You Already Made

Coding agents generate enormous context — sessions, deliverables, files, decisions. The bottleneck isn't generating more; it's finding what you already made. Here's the small glue layer I built to solve exactly that, and why grep, FTS, and RAG each miss part of the problem.

I raced 34 browser automation tools on the same five-second job

Almost every browser automation tool claims to be the fastest, the cheapest or the most reliable. I put 34 of them through the same job with the same browser and one independent pass test, then ranked them twice — because speed and real work do not agree.

Have something useful to build?

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