Things Tutorials Don’t Teach You About Building Real Applications

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.

  1. 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.
