Esri’s annual intern hackathon demonstrates the best and brightest new talent. Participants compete for the bragging rights, prizes, and the hackathon crown. Open only to Esri interns, this year marks the 11th<\/sup> annual event with 75 participants formed into 13 teams. Each team is composed of 5 to 6 members of different skill sets across Esri: developers, geographers, designers, and entrepreneurs. This cross-team and multi-disciplined approach helps foster creativity, collaboration, and execution in ways they may not experience in their usual job duties. It also challenges a team who has never worked together before to agree on an idea, quickly execute it, and win the favor of the judges, mentors, and Esri staff. Each year this proves to be an outstanding and memorable experience for everyone involved.<\/p>\n

The hackathon begins at the close of business Friday night, and all projects are due at high noon on Sunday. Each year we are amazed at the innovation and quality of the final projects completed in such a short period of time. This event lives up to its name: Weekend of Innovation.<\/p>\n

The hackathon provides valuable insight and feedback to Esri’s product teams. The use of our products and developer technology by new developers looking to push the bar and exercise our technology in new, and sometimes unexpected ways, helps drive innovation, improvements, and bug fixes to the products our customers rely on.<\/p>\n

During the initial judging period on Sunday, all 13 teams made their case and presented their working application. A judging panel votes to rank the top eight teams who will advance to the final round. The teams worked hard, but their energy was unrelenting as they tried to impress the judges. All of the projects<\/a> were outstanding and showcased well. Only a few points separated the teams, so it was a razor-thin margin to narrow down to the final eight who would advance. The finalists polished their presentation for the judging panel on Tuesday, then presented in front of a live and virtual audience of over 500 Esri employees and the six judges.<\/p>\n"},{"acf_fc_layout":"content","content":"

Overall Winner:<\/strong> Rugged Systems<\/h2>\n
