Build My Portfolio

Horrible freelancer. He promised he could recreate my Figma design with animations, but after I funded the project, the website was completely different. I wasted so much time because he kept "fixing" it, yet every revision came back with the same issues. He doesn't follow instructions and makes false promises. 1. AI-generated animations unrelated to my project. 2. Photos were off-center and poorly aligned. 3. Ignored my logo and used an AI-generated one instead. and theres more..
