When you go online to shop at a store, you often don’t think about the technology making it all happen. I mean, how do you build the next eBay? There are startups working to make your online shopping experience easier, faster more secure. This weekend welcomed the first eCommerce Hack Day organized by Dwolla and Etsy in New York City and brought together over 100 developers competing for more than $10,000 in cash and prizes. Developers had over 20 API’s to choose from and while we love to see cool hacks using Sendgrid for email notifications and parsing, teams created some really cool apps remixed with: Braintree, Paypal’s Xcommerce, Stripe and WePay for transactions Dwolla for payments between individuals Etsy, Gumroad and StoreEnvy for marketplaces Zappos for product data images, search and reviews Constant Contact for forms and email newsletters Plus a slew of API’s to make the hacks more interesting including Twilio, Mashery, foursquare, Tokbox, Terapeak, Temboo, Sincerely, Tip or Skip, Flashfoto, Kiip, iron.io and the New York Times SendGrid was a sponsor and we offered a one year subscription to Github for the best use of our API. While there were a number of teams that used the API, we could only pick one — Congratulations to Ryan and Carlos of Friendly Feast pictured here with Swift, SendGrid’s Developer Evangelist at Large in NYC, for their hack which brings together hungry co-workers and online food ordering!

The judges consisted of startup founders, developers, partners at VC firms, and tech journalists. Each team had just three minutes to demo their hack. The energy of the event was fast paced and upbeat through the weekend. Check out the full list of hacks presented on the Hacker League site.
