Hi, I'm Nino. I'm a software engineer interested in useful software, practical AI, and thoughtful product design.
I'm here to exchange ideas about building software that's simpler to use and maintain. What are you building or learning?

Before shipping an AI built feature, try the whole user flow once with an empty account.
The happy path with your own test data can hide a lot.
What catches more problems for you: reviewing the diff or using the app like a new user?

A useful check for an AI bug fix:
Run the new regression test against the old code. It should fail for the right reason.
Then run it against the fix. It should pass.
A green test suite alone can miss a test that never exercised the bug.

I've been quietly building something for the tiny tasks that interrupt a day.
Not everything needs to be smart. Some boring things should just be simple, fast, and in one place.
It started small. It isn't anymore. Any guesses?
