My advice to engineering teams is, whether you build or buy, assume your architecture will be at a 25x load within two quarters.

Who is speaking

Sachin Malhotra, Engineer at Anthropic (author of the post). Wrote about work he did on Anthropic's CI service, so first-hand; Anthropic sells Claude Code, so the account is promotional.

Anthropic sells AI or agent tools or services, so it has a reason to publish flattering numbers about AI. The passage stays in the archive; read it with that in mind.

How this was checked

Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-11-07).

Exact match in the curl-fetched page text. The page bylines Sachin Malhotra and the sentence is first-person advice, so it is his own words. I did not check the section heading separately.

To drive some long-term fixes, I started a long-running session in an internal version of Claude Tag dedicated to monitoring the service. Anytime the listener lag would get more than 50,000 jobs behind, Claude would ping me and resume our conversation on next steps.

This project took three weeks for a single engineer. A year ago it would have been closer to a quarter.

the amount of tests across our codebase grew 10x and we added a nominal amount of engineers. This all led to a 25x increase in CI jobs over a six month period
