Career
FEBRUARY 2022 - NOVEMBER 2023

At Tulip:, I contributed to three distinct applications in the retail sector, serving unique purposes: Clienteling: as a CRM tool, LiveConnect: for live chat functionality, and Appointments: for calendar and event management. My role involved implementing several enhancements across all platforms to elevate user experience and efficiency. Enhancements included adding search and filter capabilities in lists, from simple filters using segmented control to more complex ones with custom layouts and navigations, akin to Apple's settings menu. For LiveConnect, I developed features to control message limits via both dashboard and app, improving communication flow. The app was also updated to display attendant status availability and conversation chat limits. In the Appointments app, I enhanced notification capabilities, ensuring users stayed informed about upcoming events. Additionally, I integrated Twilio for batch SMS sending using concurrent asynchronous tasks, boosting productivity for associates.
