Resume

About

I'm the Lead UI Developer at Circadence. Day to day, that means leading the UI team, running our agile process, and helping product decide what we build next. I still write code too, taking new features from the React front end through to the API.

When I'm not at my desk, I'm teaching yoga, hiking Colorado's trails, or trying to settle the Oreo debate once and for all.

What I Do

Team Leadership

I lead the UI team at Circadence: setting frontend direction, reviewing code, and clearing blockers so engineers can ship. I've also designed hiring processes that were adopted company-wide.

Agile Delivery

Certified ScrumMaster running the sprint cadence, retros, and backlog. At Circadence I turned 400+ loose backlog items into ten structured projects and set up the team's first reliable sprint rhythm.

Product & Roadmap

I work alongside product from discovery through delivery and bring the engineering view into roadmap decisions. I've built dual roadmaps that keep software and hardware teams pointed at the same deliverable.

Full-Stack Features

I still build. New features go from React and TypeScript on the front end through to the services behind them, including LLM-powered tools, and I bring AI tooling like Claude Code and MCP into the team's daily workflow.

Recommendations

What managers and teammates have said about working with me.

  • If you are considering hiring, promoting, or pulling Zach onto a new project, do it! You will not regret it! Not only is Zach an outstanding developer, teammate, and coach, but he stays grounded and communicates clearly and constructively during challenging situations. While working with him on the Promotions Pod at Purple we faced heavy workloads and tight deadlines back-to-back. Zach was consistently fulfilling his responsibilities, supporting his teammates across the board.

    Kimball HeatonCAPM, CSMWorked with Zach on the same team.

  • Zach is one of the most thorough and communicative developers I've worked with. He's able to call out when things are in jeopardy and is very invested in the culture of the company. He's a great developer who is always willing to dig in and do the research as well as support his team. He has a background in project management and that comes through with how thorough he is in his documentation and how organized he is when he tackles projects.

    Katherine LiuSr. Software Engineering Manager at PurpleKatherine managed Zach directly.

  • Zach and I worked together on the Promotions pod at Purple. During this time, Zach was a Developer on the team. I greatly appreciated Zach's ability to vocalize and lead communication for the development team. This unique skill allowed us to mitigate and tackle perceived risk and issues early on. As a Project Manager, I appreciated the level of importance Zach placed on process and culture, and I was thankful for Zach's help in driving both forward with the team.
