The technical skills and mentalities required to level up in the tech industry and take on more senior responsibilities.
Becoming a 'Senior' developer isn't just about years of experience; it's about the range of problems you can solve.
### The Shift in Mentality
- **Ownership**: Taking a feature from a vague idea to a polished, deployed result without constant hand-holding.
- **Mentorship**: Helping those around you improve and writing code that is easy for others to read.
- **System Design**: Thinking about how different parts of an application interact, rather than just solving the immediate bug.
Keep learning, stay curious, and always aim to build things that are better than what you built yesterday.
