Is It Hard to Make Crypto Exchange Software with the Help of Professionals?

I'm curious to know how difficult it really is to develop crypto exchange software, even with professional help. I've heard that it's quite a complex process, but I'm wondering if hiring professionals makes a significant difference in overcoming the challenges. Would their expertise simplify the development and ensure the software meets regulatory standards, security protocols, and offers the performance needed to scale effectively? I'm thinking about investing in such a project but I'd love to hear from others who have experience.
