The system that does not exist yet
The work that has no product to buy. Private model routing, browser automation fleets, render pipelines, ingestion and enrichment, internal tools that three people use forty times a day.
Book a scope callWhat the system owns
- Model routing: multi-provider chains benchmarked on your prompt before anything ships
- Browser automation: authenticated, fingerprint-isolated, running unattended
- Data pipelines: ingest, enrich, deduplicate, and write back into the system of record
- Render and media pipelines: generation, assembly, QA gates that fail closed
- Internal tools: the small ugly interface that removes a daily hour
What gets shipped
- Infrastructure on Cloudflare Workers, Railway or your own boxes, on your accounts and your keys
- Everything under version control and handed over, no black box
- A QA gate per pipeline that blocks bad output instead of logging it
- A written runbook: how it runs, how it fails, how to restart it
Build shapes in this lane
04 patterns
Model routing layer
A provider-agnostic chain with measured fallbacks, per-model token ceilings, and a gate that treats an empty completion as a failure instead of an answer.
Browser automation fleet
Authenticated, fingerprint-isolated sessions running unattended against sites with no API, with locking so two runners never touch one profile at once.
Render and media pipeline
Generation, assembly and delivery with a QA gate on every artefact. The gate blocks a bad render instead of logging it and shipping anyway.
Ingestion and enrichment
Pull from the sources, deduplicate, enrich, and write back into the system of record with the write path idempotent so a re-run costs nothing.
Before you sign anything
- Do we own it at the end?
- Yes. It is built in your accounts, on your keys, under version control you hold. Handover includes the repo, the deployment and a runbook written on the assumption that we are gone.
- What if we already have half of it?
- Then we finish that half rather than rebuild it. The first thing the blueprint does is name what already works and stays.
- How is it priced?
- Fixed price against the written blueprint, agreed before any build work starts. If the scope moves, the blueprint is amended in writing first.

One of these is running right now.
@MiraAiHQ is a live autonomous operator built on exactly this architecture. The loop, the limits and the handoff are all documented.
