Chicago, IL815.922.7537foster.caleb@gmail.comcalebfoster.xyz

My whole career I've taken projects from idea to finish line, owning the full development lifecycle. Now I use AI to move fast, but my technical background lets me verify and fill gaps—security holes, edge cases, optimizations, systems that fall apart in production. Thrive in startups where creativity can roam free, yet equally precise when specs demand.
