For a summer internship at spanishdict.com, the world’s largest Spanish reference website, I designed and developed several features for their flagship education product, Fluencia. I made use of the company’s existing assets of audio and video sources and took the chance to learn about the latest browser technologies such as WebRTC. Later in the summer, I crafted the marketing site for both desktop and mobile devices with the goal of attracting as many subscribers to Fluencia as possible during its launch. To make the landing user experience smooth, I worked closely with the design team to perfect every pixel on the interfaces, and developed an in-house tool to track and analyze site visitor data. The new tool provided us with insights about the user experience of our marketing website and led to UX improvements that boosted conversion rate to 40% on desktop and 22% on mobile devices, from the initial 13% and 5% respectively.
