Javier Moreno

Author-page bio says Principal Engineer; co-author (with River and, per the author list, Burke Libbey) of 'Under the River' (2026-05-28) on shipping Shopify's Slack-native agent River; also wrote on SkyPilot multi-cloud GPUs and ML at Shopify.

Why their word counts: Engineer writing about a system the company built; first-hand but promotional for the employer's engineering, and the post is co-authored by the agent itself.
