I want to build a website like fiverr upwok

I built one a while back. Took me 2 weeks using Bubble.io. It had the following features: - Freelancer self-registration - Real-time chat - Algolia powered freelancer search - A reward system for freelancer

Ok, let's build! Just ensure the payment system and protection for both.

Yeah, I can second what @edward_li2 said about Bubble.io. And, if that doesn't work out, you can always hire someone from upwork to try for you ;o)
