Est. 1990 — Software & Games

Software and games by
Jim Chookagian.

I've been designing and building engineering software since 1990, and I love the creative side of it coding tools that modernize the way things are done and solve real problems.

That instinct is how this started. When I volunteered as Membership Secretary for a non‑profit fire company social club of nearly 1,500 members, I found its records living in a spreadsheet. So I built a real database. It grew into a fully customizable, enterprise‑grade membership system — secured data, automated backups to multiple locations, key‑card integration, labels, and reporting — built so almost any organization could use it. Along the way, I started making small web games for friends, family, and anyone who wants to play.

My hope is to keep building things people enjoy. Try anything here, and let me know what you think.

Membership Database

An enterprise‑grade system for managing a membership organization end to end — members, statuses, dues, roles, archives, reports, printable labels, key‑card export, and automated backups. Fully customizable for almost any club or non‑profit.

This demo runs on entirely fake, randomly generated data in an isolated environment, so explore freely — nothing here is real.
