I've been building <a href="http://DoerHub.com" rel="nofollow">http://DoerHub.com</a> for about a year and I am realizing it may be too much work for one hacker (the site is growing and I am splitting time between UX, backend, bug fixes, user acquisition features, sales, fundraising prep, and natural language processing/people search in Neo4J and Node). Looking for someone who enjoys backend performance tuning, machine learning, payments, and/or (soon) mobile. DoerHub has a dual stack (Rails on MongoDB and now adding a second stack for relational searches in Neo4j and Node). Located in the East Bay and traveling to the peninsula often.<p>The site is an execution hub - feels like a humanized version of GitHub that involves no code repository, but enables crowdsourcing and collaboration (from teaming up, to advising, promoting, task contributions, etc) on projects between hackers, non-hackers, subject matter experts, etc. We are seeing YC startup school folks and students in different departments at top universities are using it to team up around niche projects, startup ideas, and research. Ping me at founder[at]doerhub.com if you are interested.<p>Dog-fooding: <a href="http://www.doerhub.com/for/doerhub" rel="nofollow">http://www.doerhub.com/for/doerhub</a>
