I mostly answered this in another reply below, but ill rephrase it here.

The product is technically very challenging. I would never say no one else could pull it off, but the reason why they initially reached out to me for the contract was because of my tech skill set. Im the creator of a few open source tools used by well over 10,000 projects and this startup directly relates to these. I sort of hinted at my skill level, but its 10+ years professionally, typically in a lead role.
