About Me

Hi, my name is Ewelina and I specialize in software engineering and testing. My interest in logic and the process of bringing innovative ideas to fruition has been a lifelong passion. This journey began during my undergraduate studies, where I pursued a BSc in Mathematics and Economics, along with International Relations in my hometown in Poland. It was here that I was first introduced to the world of coding, and I was immediately drawn to its expressive and creative potential. After completing my degree, I embarked on a career as a Sales Representative in Cracow, gaining valuable insights into the business world. However, my passion for technology continued to grow and I made the bold decision to pursue my ambitions in London. Dedicated to the pursuit of continuous learning and skills development, I am committed to evolving my expertise in this field.
