Everyday you go into work to solve problems. It’s fantastic when you can get the issue resolved quickly but sometimes you have to sit and think about the issue, turning it over in your mind. A few weeks ago, we decided to give developers a challenge and want to share the results with you here on the blog. We had the opportunity to sponsor Apps World at Moscone West in San Francisco, February 7th-8th. It was a large event with over 5k attendees expected. Nearly every industry weighed in from banking to energy, telecom to travel, API providers to public companies with billion dollar revenues shared how they and their customers had leveraged mobile technologies and the cloud. Workshop topics included: HTML 5 – Web apps, Gaming Apps, Mobile Marketing, Payment & NFC Apps, Enterprise Apps, TV Apps, and more. SendGrid held a workshop in the Technical Briefing track on how to leverage API’s using the Arduino microcontroller. Our booth was featured in the exhibitor area alongside our partners like Microsoft, Rackspace, StackMob, and Parse. Rather than have the same old trade show setup, this time SendGrid did something a bit different. Solving email deliverability issues can feel like a puzzle, so we gave our visitors a chance to solve some real puzzles while they picked our brains about email. Those who solved the puzzles got a nice ego boost…and a sweet SendGrid t-shirt. To support the theme of mobile and hardware, we set up an Arduino board, added lights, and Swift programmed it with an alternating blink pattern. Who can say “no” to a light show? Swift hosted a workshop as part of the event’s Technical Briefing Track. He used the Arduino to demo how you could send an email using SendGrid’s API. For more info on his Arduino 101 workshop, check it out on Github and watch this video of him doing a similar demo at PennApps. We had the opportunity to show just how great SendGrid support is when a pair of Java developers wanted to see first hand how responsive we were. They launched a live chat session via the SendGrid support area which is powered by Zendesk and signed up on the spot after receiving links to our best practice docs for Email-Deliverability-101 The highlight of the event was having a packed booth most of the time. It reminds you of that circus stunt where they pull a bunch of clowns out of a tiny Volkswagon beetle. In this case it was our 10×10 booth full of developers, product people and service providers in the mobile space. We love events like this where we really get to spend extended time doing what we do best…problem solving and building relationships. We met some great people as always! Special thanks to Justin Armstrong for this great Facebook love. You can see he won a t-shirt here after solving the wooden sphere puzzle. Nice work! “Met the Evangelist team at AppsWorld today. I have to admit, they were knowledgeable, courteous, and were willing to show me about things I would have never know. I learned more today at that booth than I did from all other booths combined.” Check out more photos from the event on our Facebook page. Our Dev Relations team is always out on the road, so be sure to check out our Event Calendar to see where we’ll be next. Upcoming stops include MongoDB LA, Heroku Waza and Geeks on a Plane India. We’re also hosting a party at SXSW and are sponsoring PyCon in mid-March. Hope to see you there!
