I have a friend who's looking to hire someone to quickly prototype a web app of a similar complexity to angellist. He's mostly concerned about working with someone who's experienced and fast, and it could potentially continue if all goes well. Sorry I can be more specific. Let me know if anyone has experience in rapid prototyping for web

I have experience on quick prototyping. Is it more backend/frontend prototype? Does the technology implemented in matters? I’ve experience on Ruby on Rails

Ok! I’ll ask

granted it was a long time ago, but angellist did start as an email list. what fidelity is required for this person's mvp?

Pretty high fidelity, I think
