Eric Polley / Software developer

I’m the sole developer behind every project here: internal tools that connect people, data, and workflows, and creative applications that turn ideas into something you can use.

How I work

My workplace projects begin with the people using the software: how an item moves through a warehouse, how a host runs a show, or what happens when a customer buys two giveaway turns. As the sole developer, I own workflow design, implementation, integration, and testing. I use Codex as part of my development process and refine behavior through testing and real operational feedback.
