StyleCut

StyleCut: a pnpm monorepo covering a web app, an entitlements package with Ed25519 offline licensing, a payments package on ZiniPay, a style engine and an admin tool. Renders video through a style compiler rather than assembled command strings.

Private Client Repository

This software was engineered for a private business or client organization. If you are a hiring manager, technical lead, or potential client wishing to inspect the architecture and code quality, I would be pleased to grant you access or provide a code walkthrough. Please contact me at [email protected].

The Engineering Challenge

Video effects assembled as ffmpeg command strings break in ways that are hard to see — a quoting error or an argument order change produces a different video, not an error. Licensing also had to survive a machine being offline.

The Solution & Architecture

Renders go through a style compiler that builds the filter graph as data rather than as concatenated text. Entitlements are Ed25519-signed and verified locally, so a paid feature keeps working without a licence server to call. The monorepo splits entitlements, payments and the style engine into packages so the web app and the admin tool share one implementation.
