About

Hi, I'm Roberto Hernandez — a programmer, entrepreneur, and author. I write and teach about programming, productivity, self-improvement, and online businesses, with an emphasis on learning from failures and personal transformation.

MullinStack is my space for sharing resources and tools for both the programming journey and lifestyle development. I believe in building greatness collaboratively and leaving a positive impact.
