Through the years, I consider myself to be a hard working, reliable and enthusiastic person with high standards and the ability to learn new skills quickly. I enjoy working both independently or as part of a team, consistently achieving required goals. Throughout my work experience, I deeply understood both user design issues and the underlying core technology.
