Looks good overall. A few suggestions though. To note, viewing this in mobile.

Have the fixed header bgcolor fade in before the logo hits the first block of text on scroll.

Change the green text inside the skill tags on the freelancer containers. Black, white, or another dominant text color on the page. Green on red looks too christmas/watermelon-y. They're complementary which can make elements pop, but can also look muddy. Idk just a preference.

Try using a photo of a freelancer looking in the direction of the call to action. Studies show that users are drawn to the eyes of people in images and the direction those eyes are looking in, which results in more signups/carrying out desired action. If you want users to click on the photo of the freelancer looking straight ahead, then that image works great because users will lock into a gaze with that image, but not if you want them to interact with another element on screen. In that case you want to use someone looking towards the element that you want people to interact with.

*Just noticed, after writing this, that the photos are clickable/tappable.

Lower border radius on email input and/or have it be focused on landing. Looks too similar to the button and reduces attention/increases cognitive load because users will perceive it as having to immediately make a choice between two things. Don't Make them think.

Would maybe treat the "As mentioned on" section similar to the "Our freelancers worked for". People seem accustomed to seeing that design treatment for clients/mentioned sections and at a glance could elevate credibility/perception. But it's not a big deal, it visually looks good as it is.

Personal preference, ditch the chatbot or dont make it active/keep it closed on landing (let the user choose to see it/use it). My assumption has been that they likely increase bounce rates (there are plenty of marketing articles that say otherwise), due to the amount of space they take up when active on landing and how distracting/annoying they are when they "pop up" like that. It just gives the same vibe as having audio active and playing on landing. But that's an assumption, what do I know? Analytics / A/B test could prove otherwise.

Just briefly looked at the freelancer profile screen and the inputs at the bottom are confusing and crop/hide information requiring scrolling read everythinf. Displaying information in textareas will make users think that you want them to sign up as freelancers, also gives the impression without reading that a task is being asked of them. Don't make them think or work, guide them to signup.

The information in the textareas also appears to be duplicated from info above. I'm guessing that the top profile section is to appeal to clients and the bottom for freelance talent to signup? If that's the case, maybe give users the option to select whether theyre a freelancer or a customer/client? I know I said don't make them decide on options/think, but this might be necessary for the two use cases. It could be done in a way tho where it doesn't look as much of a task as it would a nav element. Like having a signup container/modal that has a tab for both types of users, but on load have the business's priority user active. Or if you're showing an example screen, maybe tab that screen even to differentiate the multiple uses and provide convenience for comparing (people are likely to be curious to compare).

Edit: To add, agree on the name being a little confusing. Could give the impression that the site is about gender, especially at a glance in search results. Even on load, some may just see "cis" and the profile pics, and think it's a non-binary dating site. Not hating, just pointing out an issue of potential user perception not matching business goals.
