321 Enterprise Labs

Small tools, useful experiments, and ideas in progress.

A home for the software I'm exploring, building, and sharing along the way. Some projects are polished utilities, others are early prototypes, and a few may eventually grow into standalone products. They're all built from real problems, genuine curiosity, and a belief that useful software should be simple to use and easy to share.

    QR Code Builder

    Codes that survive being printed on something and scanned in bad light.

These came out of the client work.

Every tool here started as something I needed on a real job, and two of them grew into their own products. The client work is where they come from — brand identity, websites, and email that has to survive Outlook.
