Acomplishments
I led the design and development of a NextJS website for a sports event planning & race timing company. The project involved UX design through wire framing, focusing on maximising race registrations and client acquisitions, and ensuring race results were accessible via user-friendly result tables. I managed the art direction and UI design, to create an on-brand and aesthetically pleasing website. I built the website from scratch using NextJS & integrating Sanity headless CMS to allow for updating content, image, upcoming races & race results.
From planning to delivery, I led the frontend development of a key feature for a comprehensive an all-in-one communications platform (sales, marketing, customer support). A re-usable & interactive filters table built using ReactJS. This project required collaboration with backend engineers to enable users to add & combine filters and sorts on columns. Filters included text search, value matching & date ranges. Users could take actions on single table rows or select multiple rows and perform bulk actions. To ensure efficiency with large datasets and to maintain user engagement, the table was virtualised.
