Abstract Driven Development V3
abstractdriven.com · MIT
An open-source architecture method. Every module at every depth has the same five layers, so the dependency rules follow from the path.

6 systems,
every one of them in production.
We take on .NET and Rust backends, web, mobile apps and AI integration, then containerise and run the result ourselves after handover. The six systems below serve real users, each one with the algorithm at its core taken from its own source.
- 6
- systems in production
- 3
- with a public deployment
- 4
- techniques reused
- 26
- technologies in the stack
§ 01CORE TECHNIQUES
4 techniques we reuse across systems
Every technique here has reached production at least once. The product names below are where it runs.
01
Five-layer fractal architecture
Every module at every depth has the same five layers. The dependency rules follow from the folder path, so nobody has to look them up. New engineers and AI agents both find their way.

02
Business rules written as state machines
Valid states and valid transitions are declared in code. An illegal transition returns an error carrying the source state and the event, instead of quietly writing bad data.
(s, e) ∉ δ ⇒ Err(InvalidTransition { from: s, event: e })03
Stacked fallback tiers
AI providers meter on several axes: per account, per project, per model. Each axis becomes its own fallback tier, and the tiers stack, so a long job does not die halfway through.
profile → project → model04
Computation moved into the browser
Rate sheets and credit limits should not pass through our servers. The business core is Rust compiled to WebAssembly, and what the client receives is a folder of static files.

§ 03SELECTED
3 systems worth reading first
Three different kinds of evidence: source you can read, a system built for a client, a product we run ourselves. The table above is the full catalogue.
LBS · Internal shipment tracking
lbs.com.vn · app nội bộ
An internal shipment tracking app for LBS Global Logistics. Reading Excel, checking constraints and moving states all happen inside WebAssembly, on the staff member's own machine.
