Alex Carter builds the developer and converter tools at AT USE — the JSON formatters, regex testers, network lookup tools, and the 50+ format-pair image and file converters.
Before building tools professionally, he spent years on the receiving end of them: debugging DNS propagation at odd hours, converting images between formats before client handoffs, running ad-hoc SPF record checks while troubleshooting email delivery. The pattern kept repeating — reach for a tool, hit a paywall or a sign-up form, search for an alternative.
The tools at AT USE are his response to that pattern. Server-side processing, no retained files, no accounts. They do one thing well and get out of the way.
