Over a two-month period, Fqtugs19 contributed to the erxes/erxes repository by building and refining key frontend features focused on deal and pipeline management. They upgraded the deal priority selection component, replacing legacy code with a more usable SelectDealPriority and updating GraphQL mutations and subscriptions to ensure accurate, real-time data flow. In addition, Fqtugs19 enhanced pipeline configuration by improving drag-and-drop reordering and sortable attributes, and introduced UI improvements such as MoveDealDropdown and advanced search for deals. Their work, primarily using React, JavaScript, and TypeScript, emphasized maintainable state management and addressed workflow pain points without introducing unnecessary complexity.
