Hi, I'm Faisal 👋

I built Flatliner because I was tired of trying to write CPR notes after a code.

I wanted something fast, clean, and practical — built by someone who knows how hard it is to reconstruct a code after it ends.

What started as a personal project became a way to reduce documentation stress and make post-code notes easier to complete.

I'm still improving Flatliner based on feedback. If it helps you stay focused when it matters most, then it's doing its job.
