Software Engineer III at McDonald's · Always building

By day I'm a Software Engineer III on McDonald's global web ordering platform. The rest of the time I'm shipping my own projects: AI publishing pipelines, automation tools, and fast, search-friendly web apps. This is where I share what I build and what I learn.
