In my past life, I worked as Automation Program Manager for a large company (Market Cap $14B+), designing and managing VBA and Python-based tools, ultimately saving the company over $4M / year in increased efficiency. As I built more software automations, I watched more peoples' jobs vaporize in thin air... Eventually, I couldn't take it anymore. I didn't want my software skills to be used lining shareholders' pockets, while my co-workers lost their jobs. Then I realized: Rather than automating jobs away, I could free up small business owners to do what they're passionate about, instead. And so, here we are! This feels like a much better way to put good out into the world. I like to take on projects which excite me. I have over 15 years of web/software development experience under my belt, and love bringing that to the table to help people create new, awesome tools.
