Feedback

The work
speaks back.

Unfiltered feedback from people who trusted me to build and ship.

Great developer! Worked very fast to fix my ChatGPT API Zendesk App for use. They updated the model and API keys and was able to help troubleshoot the issues as to why it was not previously working. Thank you!
