You love building elegant user experiences, tackling impossible problems, and you have a passion for the customer experience. You enjoy learning new things and creating life-changing applications. You possess strong skills in object-oriented software design and debugging. You are excited about developing new features, maintaining existing code, fixing bugs, and contributing to overall system design.
