Shared widget library for market finance

## Context

Minotore builds software for market finance. I work on the frontend team, where a shared library of widgets serves 8 projects from an Nx monorepo.

## What I did

• Built 76 reusable, accessible widgets with RxJS and Signals, shared across the 8 projects.
• Cut widget size by 30–50%.
• Supervised the migration of 68 widgets and 8 libraries from Angular 18 to Angular 21 / Nx 22 in one 3-week sprint, leading 3 developers, and contributed to the Angular 22 / Nx 23 migration.
• Introduced Vitest: about 9,000 tests with 80–96% coverage.
• Built a Storybook skeleton library and the Keycloak authentication screens.
• Mentored 2 new team members and 1 intern.
