Daniel Spinosa is an agentic engineer and founder with 15 years of experience building web and mobile products, leading startups, and shipping production systems from infrastructure to UX. He’s repeatedly worn CTO and CEO hats—founding Shelby.tv and Overtime Media, leading engineering at FoundersCard and Medly Pharmacy, and co-founding Fixable to bring telehealth-style service to home improvement. Comfortable across Ruby on Rails, real-time stream processing, video systems, and hardware (he holds a newly granted patent for Electrotiles), Daniel combines hands-on coding with strategic product and business leadership. Based in Dripping Springs, Texas, he now focuses on agentic engineering roles that help others build faster and better. He has a track record of turning prototypes into scalable services and enjoys tackling problems that sit at the intersection of product, operations, and delightful user experience.
