Welcome to the new edition of GeekOnPeak.
Cloud & AI infrastructure, to be written in the open

Notes from building real systems, shipped to real clients.

I'm Kritish. I run Kyrex and ship cloud and AI infrastructure for working businesses. GeekOnPeak is the long-form record of what I learn: case studies of production builds, and the posts that explain the moving parts. Everything here is free to read.

IN BUILD · ~2 WEEKS

One build not being named yet.

The one worth waiting for. It is on the bench now and the write-up follows about two weeks behind it — including the parts that did not work, which is most of what made it worth writing.

Waiting list

The newsletter is not running yet.

It starts once there is enough here worth sending. Leave an address and you go on the waiting list: the first issues reach you before general signup. Everything stays free and stays on the site — there is nothing behind the email.

No email until the first issue. One address, held by us, nothing else.
