## About

```text
At BrainRocket, I own the shared UI component library and its SCSS/BEM architecture, used across the platform’s applications. I work with designers to shape components from early exploration through API definition and documentation.

I also develop a React 19 and TypeScript back-office application and write solution designs for plugins on a new widget platform. Its platform-agnostic core runs in the browser and inside a Flutter mobile app through an embedded QuickJS engine.

As Release Captain for my stream, I’ve shipped more than 100 production releases and established release, Git branching, and code-style conventions. Before BrainRocket, I led a marketplace redesign at REnumber Lab and built financial dashboards and subscription features at NumFin Global.
