Building at the intersection
of two worlds.
I'm Sachin Rai - an enterprise sales professional who became obsessed with the infrastructure question underneath every AI deal. Not the pitch. The reliability work between a chip and a quota.
By day I work in enterprise sales at Freshworks, closing Freshservice deals with IT teams across the region. By evening I build: trading systems, knowledge pipelines, AI agent stacks. The blog is the overlap.
Field notes means what it says. These aren't thought leadership posts polished for LinkedIn. They're records from experiments that ran, and a few that didn't.
