Over a two-month period, this developer delivered two features across nextcloud/notes and ofkm/arcane, focusing on both backend and frontend improvements. In nextcloud/notes, they implemented API v1.4 image attachment endpoints using PHP and JSON, enabling users to upload and retrieve images tied to notes, which enhanced media support and cross-client integration. Later, in ofkm/arcane, they built a theme customization feature with a Svelte-based UI, allowing users to select and persist themes globally throughout the application. Their work demonstrated a full stack approach, combining API development, UI/UX design, and collaboration to improve user experience and application consistency without addressing bug fixes.
