I am a Software Developer, with skills focused on frontend as well as backend side. I have experience working with scrum teams and developing React web application with different technologies applied to projects. I am highly efficient with strong communication skills which enhances problem solving and development velocity. Along with my brother, who is a UX/UI designer, we develop and actualize our ideas to simplify day-to-day problems.
I had the pleasure of working with Jakub for a year on our frontend engineering team at Brainly. During this time, he consistently demonstrated a strong skill set in migrating and creating React components, unit testing, and storybooks. Additionally, Jakub had a good understanding of E2E tests using Cypress and Cucumber and had experience with GraphQL and Apollo. What really impressed me about Jakub was his ability to effectively communicate and collaborate with the rest of the team. He has a positive attitude and is always willing to help out and contribute to the success of the team. I highly recommend Jakub for any mid-frontend engineering position. His technical abilities and team-oriented approach make him a valuable asset to any organization.
