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.

Receipt Relay
Photograph a paper receipt and get a real transactional email back. A vision model reads it, flags what it isn’t sure of, and you check every field before the email is built.

Campaign UTM Builder
Tagged links that stay consistent across a campaign, so the analytics are worth reading afterwards.
These came out of the client work.
Every tool here started as something I needed on a real job, and one of them grew into its own product. The client work is where they come from — brand identity, websites, and email that has to survive Outlook.
