After working on multiple real-world applications, one thing has become clear to me: Tutorials are useful, but they only cover a very small part of what it actually means to build software.
Real applications expose challenges that tutorials rarely address — not because they are unimportant, but because they are hard to simulate in controlled examples.
- The Hard Problems Are Rarely About Syntax
In real systems, bugs are rarely caused by not knowing a language feature.
Most problems come from:
- Incorrect assumptions about data
- Misunderstood requirements
- Unclear ownership between services
- Edge cases that were not considered
Syntax can be learned quickly. Judgment and system thinking take time.
