I built apps for 9 years. I made mistakes. Some were small. Others cost me sleep. These failures taught me more than any course.
Optimizing too soon. I tried to make systems future-proof. I added layers for problems I did not have. This created too much code. Plan for scale. Earn your complexity. Solve today's problems first.
Ignoring the database. I focused on APIs and frontends. I ignored the data design. Queries slowed down as data grew. Database design is a top priority. A good schema saves months of work.
Skipping monitoring. My code worked in development. It failed in production. I had no logs. I had no alerts. Debugging was a guess. Observability is a requirement. Your system must answer: what failed?
Building features instead of solving problems. I loved adding features. Users do not care about the number of features. They care about results. Simplify workflows. The best features are invisible.
Underestimating communication. I thought technical skill was everything. I was wrong. Communication is equal to technical skill. Explain your trade-offs. A solution fails if the team does not understand it.
Now I ask four questions:
- Is it simple?
- Is it necessary?
- Is it easy to maintain?
- Does it solve the problem?
If the answer is no, I change the design.
Experience comes from failure. I learned through mistakes. These lessons are my most valuable assets.
What lesson changed your approach?
