About James

Previously I was a successful options trader on Wall Street. Aside from trading, I managed a regional office - ran teams, designed and build internal software products, and trained new traders. 2012, after I felt the HFT strategies had sufficiently disrupted the options market making business and turned my focus on startups. I worked for HireArt, a YC funded company as their first Ruby on Rails developer. I played a large part in everything from product to design and coding.

Last year I tried launched a subscription e-commerce business but I could not get it to scale. Learned a great deal from the experience.

I'm a full stack iOS and RoR dev - can do everything from database design to front end implementation.

In my spare time I play basketball, snowboard, bike and travel (30-40 countries?). Movie and theater geek.
