Detail of the Engineering 3.0 pipeline diagram: a product owner writes the ticket, the agent — highlighted as the only author — implements it on one branch per ticket, and every task auto-deploys its own proxy-routed preview stack. Below, the review row runs pull request, engineer, final QA and tech lead.
Featured · Engineering 3.0 · Team architecture Scaling a non-technical team on agents The agent writes every line; four human seats can each say no, and only two of them read the diff. A product owner writes the ticket, every task auto-deploys its own preview stack behind a wildcard proxy, QA returns findings as prompts rather than patches, and a release tag is the only road to main.

Featured · Agentic AI · Local pipeline Automated news & media pipelines Agentic AI turns a forecast into a finished weather-news reel — script, narration, visuals, final cut — with no human in the production loop. A person only approves it before it publishes, all on a home computer. Read how it's built →
broker_parrot's Flight Deck panel: three hosts side by side with live CPU, GPU, memory and disk gauges, per-queue worker toggles and an hour of thermal and power history each.
Featured · Open source · Python broker_parrot — a self-hosted job fleet A workflow engine that makes the database you already run the whole broker — no Redis, no RabbitMQ. It claims jobs with SKIP LOCKED, heals crashed workers through expiring leases, and runs DAGs on a durable outbox. Defaults to SQLite, so the smallest setup needs no server at all.

A dedicated machine by the hour — one tenant at a time, billed for the hours you actually use. No minimum term.

An isometric H200 SXM GPU module, its finned heatsink standing on the board, above two flat DGX Spark slabs joined by one cable.
