• You have a high degree of initiative, creativity, persistence, and a strong focus on producing tangible results quickly and pragmatically.
• You love learning about new technologies, but love building real products more.
• You care about the long-term maintainability of the codebase and will learn to advocate for refactoring and clean-ups where appropriate
