I build practical software, from production websites to automation and engineering tools.

I built and deployed senorapapa.com, a five-page production website used daily by customers for menu and takeout information. I hand-wrote the HTML, CSS, and JavaScript, including menu filtering and a live open/closed indicator.

At Adventec Manufacturing, I owned two product programs from requirements through build, validation, and release. Previously, I improved dimensional-reporting efficiency by 45% by building Excel VBA tooling for Mitutoyo MCOSMOS output.

My engineering work includes CMM measurement routines, root-cause analysis, manufacturing design feedback, and permanent corrective actions verified in production. I also built an internal QA database search engine in Microsoft Access and VBA at Colortech.

I've developed software in Python, JavaScript, C++, and Excel VBA across roles in manufacturing, research, education, and consulting. My University of Waterloo Computer Engineering education included algorithms, data structures, functional programming, and numerical methods.
