Exhibit 01 · Media
The Video Factory
An operable model of how an upload becomes protected, adaptive video, and why moderation and licensing are part of the pipeline, not afterthoughts.

Machines you can run
An experimental space for understanding how digital systems work. Change the input, run it, and watch what follows.
Exhibits
Operable models of systems I have built, each linked to its case study.
Exhibit 02 · Developer Infrastructure
The Verification Foundry
An operable model of Dino: discover an API, sign in without the agent ever holding the secret, a human approval, autonomous testing under budgets, and a sealed result anyone can check.

Exhibit 03 · Intelligence
The Sparks Dynamo
An operable model of Circo Sparks: every interaction becomes one kind of event, every event splits into a fan value and a creator value, and the day rolls up into a summary for the post.

Exhibit 04 · Leadership
Engineering decisions
Make the call yourself: two real design decisions, each with its options, its trade-offs and what was actually built.
JudgementTrade-offs
Exhibit 05 · Media
The Cinema Vault
Encrypt once, license per viewer. Every player can fetch the encrypted film; only the licence decides who can watch, and the licence asks who has paid.

Exhibit 06 · Media
The Moderation Lab
A video admission line that probes cheaply, gates on spec, classifies with a model and always returns one result contract, rejecting what it cannot inspect.

Exhibit 07 · Intelligence
The Recommendation Engine
Interactions are batched in, a feed is requested per viewer, candidates are ranked by interest, and a visibility rule serves only what is published, processed and not deleted. A view attributes back to the session that produced it.

Exhibit 08 · Fintech
The Financial Exchange
Money moves through channels and every movement is a balanced double entry: two ledger columns that must stay equal. An idempotency key keeps a retried payment safe, and settlement is separate from access.

Exhibit 09 · Media
The Broadcast Tower
A scheduled premiere simulated from a recorded upload: the playlist reveals only what has aired, late viewers land at the live edge, and nobody can skip ahead until it ends.

Exhibit 10 · Leadership
The Engineering Workshop
How AI-native engineering runs here: a human sets the rules, agents build inside them, deterministic gates and human review stand before production, and findings feed back into the rules.

Experiments
Small, bounded models of one phenomenon each: a single idea you can change and watch.
Experiment 01 · Developer Infrastructure
The Cache Shelf
A small cache in front of a slow origin. Change the eviction policy, the shelf size and the request pattern, and watch the hit rate move.

Experiment 02 · Developer Infrastructure
The Retry Storm
Four clients, one server and a brief outage. How the clients retry decides whether the server recovers when it comes back, or stays buried.

The Message Relay
One message, three ways to carry it. Take the recipient offline and see which designs still deliver, and what each one has to keep awake.

Experiment 04 · Media
The Swarm
One video delivered by its own audience. Change who is watching and when, and see how much peers carry, how much needs an always-on node and where it stalls.
