Hello, I’m a developer working on tools that help content creators understand and grow on YouTube. Recently, I built a simple YouTube Watch Time Calculator that helps estimate how many views and hours are needed to reach monetization goals. I’ve been testing and improving tools like this on my site, and I thought it might be useful for others here who are working on growing their channels.

I love that phrase you used “joyful overengineering.” That’s exactly what it feels like sometimes. :)
Yeah, I’ve had that moment too. I once added strict validation to a pipeline just as a “future me” thing. Felt unnecessary at the time. Later, an API changed slightly, and instead of silent bad data, everything failed loudly with a clear error.
