Kode Stack Demos

Rails 8.1.3.1 · Hotwire (Turbo + Stimulus) · PostgreSQL 16 · Sidekiq on Valkey, deployed to AWS App Runner from a container image. Three small demos of a medical-coding workflow. Synthetic data only.

Demos

Chart queue

Coders claim synthetic charts from a live shared queue; row locks keep two tabs from grabbing the same chart, and a job releases claims that blow their SLA.

Review workflow

A coded chart moves from draft to review to returned or approved, with inline edits, a full audit timeline, and keyboard shortcuts for the reviewer.

Coding assistant + evals

A background job sends a synthetic encounter note to a model and streams suggested codes back with confidence, and an Evals tab scores it against a golden set.
