Builder obsessed with creating consumer products that make real-world impact.
Mission
I build things that matter.
My goal is to create technology that genuinely improves people's lives. Whether it's democratizing phone service at TextNow because communication is a right not a privilege, giving less fortunate people access to full computer environments through Cluo, or empowering founders to bring their ideas to life with Launchit - every project I take on starts with the same question: how can this make a real difference?
