helped this company grow twice the size in ____________ months

Last summer, I worked at Highrise Pet Care as a Front End Engineer Intern. Under the collaborations with designers and the product manager, I designed and developed two collaborative hybrid mobile applications as technical solutions for current business. I actively participated in every step of the developing process. Specifically, I enjoyed interviewing with customers and testing the apps with them because I can get a clear picture of where to improve and what's their real requirements. By doing that, I was able to developing user-centered applications with pleasing and intuitive user experiences. Also, although this was my first time using Ionic Framework, I learnt it by myself quickly and was able to fluently use it within a week.

These apps helped the business grow twice the size in a month. Besides that, what I learnt from the internship is more than just how to write clean and scalable code, I also learnt how to see a product from different perspectives and how to effectively work in a cross-functional team.
