got scammed with the front end. they kept trying to delay work. the delays then were tried to be blamed on me which I could prove. I built the front end and still wanted to scam me. I asked them so much stuff to do and they sent me files that was not done. called me a liar and I could prove it was done....

First step was completed successfully with a high-quality ui ux design for the app. He is very talented and knows how to create engaging and modern interfaces. Every section was thoughtfully designed with strong visual balance. Definitely interested in starting the flutter frontend development phase next.
