Callback Widget for InPost

As a frontend developer at Yarrl, I built the frontend of an InPost widget that lets customers request a callback or book a time slot for a conversation.

Key solutions

Web component architecture
Full responsibility for the architecture: a complete web component (@angular/elements) with Shadow DOM isolation and runtime configuration via HTML attributes.
Self-contained bundle
Optimization of a self-contained bundle (inline assets, fonts, and translations) without additional requests.
Accessible reactive forms
Reactive forms with dynamic validation and keyboard-accessible dialogs (a11y).
