Side profile of Zachary looking to the left

Hi, I'm Zachary.

Summary

I'm a multidisciplinary problem solver with 20+ years' experience.

I craft digital solutions that are usually, but not always, on the Web and use modern tools with an emphasis on tool-building and efficiency.

In my career I have operated in several capacities around the craft of software engineering. I've worked on almost every layer of the web stack at some point in both junior and senior roles including architecting and leading projects.

Along the way I've helped teams and colleagues grow their skills through better documentation and my own personal style of mentorship, which is generally in the form of patient, individual teaching (with books/docs recommendations) based on my observations of their work. I also enjoy AV production so I've also made screencasts in the past for broader knowledge sharing or occasionally "lunch and learns".
