It starts simple.
One simple task. Then another. Then another.
Analyze the environment
Understand the existing system
Identify dependencies
Define the trigger
Design the process
Build the backend logic
Build the requests
Handle the data
Validate inputs
Control access
Secure data exchanges
Handle errors
Test the process
Test edge cases
Fix errors
Verify the result
Optimize the process
Prevent duplicates
Deploy and monitor
A single addition may seem simple. Building it properly is much less so.
Still “just one more task”?
