The maker behind the mark
I’m James Shelby, an independent iOS developer from Salem, Oregon.
My path to software ran through emergency medical work, private security, and more than seven years in knife manufacturing. Each taught me the same lesson: details matter, dependable tools earn trust, and good work should have a clear purpose.
Dagger Development brings that mindset to software—focused products, thoughtful interfaces, and steady improvement with every release.

Every app starts with a clear problem and stays centered on solving it.
Typography, interaction, privacy, and performance are part of the product—not polish added later.
Useful software is shaped over time through real use and honest feedback.
