Profile bio

About Kerry Ritter

I'm a product-minded engineer and CTO/Co-founder at Zipper, where we're building AI-powered marketing and booking software that makes agency-quality growth accessible to small businesses. I'm passionate about combining quality engineering with real customer value, creating technology that meaningfully impacts business owners' lives.I believe in mastering the entire technology stack—from crafting intuitive user interfaces to building resilient APIs and deploying scalable cloud infrastructure. While my journey included years of ASP.NET/C# and PHP development, I've found my ideal toolset in full-stack TypeScript with tools like NestJS, React, and Remix.My programming journey began in my pre-teen years, tinkering with Geocities, HTML, and PHP. This early passion led me to pursue a Bachelor of Science in Computer Science with a minor in Mathematics at Southern Illinois University Edwardsville.Throughout my career, I've worn many hats: startup engineer, development team lead at agencies, senior engineer at Microsoft, application architect, technical director, and now CTO. These experiences shaped how I approach building technology that solves real-world problems - be prepared for scale, build for now, focus on your user.I contribute to the developer community through open-source tools and libraries at https://github.com/beermoneydev and mentor developers and organizations at https://mentorcruise.com/mentor/kerryritter.

Listed skills include Javascript, Php, Css, Html, and 24 others.
