Senior Software Engineer · Orange County, California

I work on web apps, databases, and internal tools at Design West Technologies. A lot of that means getting newer software to work with the manufacturing systems already in place.

Here’s a bit about my experience and some of the things I’ve worked on.

Some of my work

All projects

A report took about 35 seconds to run. After some SQL and backend changes, it was down to roughly 2.

These are brief write-ups. I’ve left out internal details that aren’t mine to share.
