Creating AI API for integration with EasyWeb landing page builder
I'm glad I managed to find such a responsible person who loves to see things through to the end, giving their maximum effort. Unfortunately, I was not able to fully train the AI to meet our requirements (the requirements grew during the process), but I am more than satisfied with the current result. We continue to work and improve our project, and to everyone reading this - I recommend contacting this freelancer! This is one of the few cases where a person is interested in doing their job well, rather than just getting paid as quickly as possible regardless of the outcome!
