I am a dedicated software developer with almost seven years of experience in full-stack web development and SaaS products. So far, I have appreciated the opportunity to contribute to team efforts through mentoring junior colleagues and working closely with leadership, including C-level executives, to accomplish project and business objectives. I am now seeking to apply my skills within a Swiss-based team and am enthusiastic about relocating and integrating into Swiss culture, including learning German, French, or any other languages if needed. As a self-taught developer, I have learned independently and adapted quickly to new technologies through documentation and online courses.
