Veerle Eeftink - van Leemput
You can definitely call me a Shiny enthusiast, and I hope I can make you just as excited about Shiny as I am. Ever since I graduated as a Data Scientist back in 2016, I am obsessed with software development. I always liked building something tangible. Something that people can use every day to make their work just a bit easier. An application holds the power to truly turn data and analysis into insights. Numbers don’t have to be boring! My weapon of choice: Shiny applications.
After working for a couple of years as a Data Scientist in various industries, I felt it was time to bring my vision to life: helping others to leverage the potential of Shiny to build amazing applications that help to convey a message. I established Hypebright in 2019 and since then I focus on providing training, workshops and consultancy related to R and Shiny.
I’m a true believer of learning by doing, but I also don’t feel like developing “Hello, World!” applications is something that will stick. Building simple demo apps never really worked for me. The learning starts when you’re building something real, something that has a story. It needs to be exciting and it should translate to your own work.
I developed the courses with exactly that in mind. I want you to build something useful, and I want you to be involved in that process. It’s not about showing you how I develop an application or a Shiny package. It’s not about me at all, it’s about you! I want you to become a co-developer. And by the end of a course, I want you to proudly say, ‘I developed my first Shiny app or package!’
So join me on our Shiny adventure and let’s build something amazing together!
