Inside the product
Seniority isn't about knowing more.
It's about deciding better.
In this book, you'll reflect on:
- Real trade-offs in technical decisions
- Architecture as a compromise, not a diagram
- Bad code as a symptom, not a cause
- Technical debt as a strategy — or neglect
- The impact of decisions on the team
- Thinking about systems, not tasks
This isn't a tool manual. It's an invitation to technical responsibility.
