ABOUT COOPER

An engineer’s approach.
An operator’s perspective.

I’m a full-stack software engineer and startup co-founder with a background leading live production teams. I turn complex business workflows into dependable software and own the systems that keep them running.

WHAT’S NEXT / 2027

Consolidating under Barrel and Bit.

In 2027, I’m bringing my independent software and hardware products together under Barrel and Bit—absorbing Tone Capsule as I conclude my tenure as CTO at the end of 2026, alongside Uplink LMS and Upfront Games.

Before building cloud software platforms, I led a team of 90 contractors and volunteers at Eastside Christian Church and served as the primary on-call resource for critical system failures. That role was also where I started writing production software—engineering Q-SYS Lua hardware drivers for Christie and Sony projectors, daisy-chained Sony Bravia displays, and Yamaha TF consoles, along with macOS OSC/UDP bridges and console safety interlocks so volunteers could run complex rooms reliably.

At Studio Kids Management, I’m the sole engineer behind three connected Azure applications spanning internal staff operations, family onboarding, and the public website. The agency moved from paper tracking and a system that retained only one project’s progress to managing 90+ active projects on a largely automated platform. I own the full stack: business workflows, legacy-data migration, identity, encrypted records, private database networking, and deployment.

As co-founder and CTO of Tone Capsule, I took a product from vintage telephone hardware to a working audio guestbook business. I built the Raspberry Pi runtime—later rewriting the original Python services in Go on headless Linux for faster cold boots and lower thermal overhead—alongside cloud synchronization and the customer portal, then helped bring it to private events and a wedding expo. That work connects embedded devices, web applications, and the practical demands of putting a product in customers’ hands.

Today, as a Systems Engineer - Studio & Applications at Stacks Bowers Galleries, I bring those disciplines together for live auctions. My work includes integrated studio controls, internal applications, and modernizing inherited software with the infrastructure and development teams.

Azure is my deepest cloud platform; I also deploy to Google Cloud and self-hosted Linux environments. I use AI tools to accelerate engineering while owning the architecture, reviewing the code, and testing the result. In products, that means permission-aware assistants and human review before proposed changes take effect.
