New businesses require interactive and complex user interfaces to promote usability, user retention and satisfaction from experiencing the platform. The days of server-side rendered websites that load pages on each refresh are long gone. Now users expect the web applications to interact seamlessly, provide immediate feedback, and quickly transition between different views. I aim to help you do exactly that, build complex user interfaces that are both fast and delight your customers. I use the same technologies as the companies like Facebook, Netflix and Amazon use, in order to deliver great experiences to their visitors.
