The main goal of this thesis was to develop a web application capable of querying professional social networks for new talents. The application was succesfully created according to user requirements of Talent Acquisition Team in Red Hat Brno. It was fully tested and it will be deployed in the company. The thesis was not only focused on programming skills. It was also about a communication with end users and UX team in Red Hat, which provided consultation about the UI design. I gained experience from all phases of software development process. The technologies and programming languages used for developing the applicationwere completely new for me. I have proven myself to be flexible enough to handle all of these challenges.
