Instructor for a pilot Web Security Ambassadors course that CodePath ran at Facebook. The program was a success both in terms of learning objectives and student satisfaction, and was launched to a wider audience the following year.

Cerego is an education technology company that quantifies your knowledge while helping you learn faster and remember longer. I had the privilege of leading an amazing engineering team in creating a great product with a solid learning science foundation.Among other contributions, I played an instrumental role in:- Hiring up an engineering team from scratch- Rewriting the entire site to be API-driven- Overseeing the development of iOS and Android apps- Internationalizing and localizing our site and apps- Implementing automated scaling and no-downtime deploys- Refactoring and cleaning up over 500,000+ lines of legacy code- Maintaining site uptime and responsiveness through major transitions- Building strong culture and togetherness, growing company from 4 to 20 employees

In the glory days of the digital currency Bitcoin, Kevin Meehan and I founded BitSaloon - a provably-fair online casino. We designed and built the entire site ourselves, including multiplayer poker, video poker, roulette, hi-lo, a lottery, a sportsbook, and account management, reporting, and payment systems. Due to the uncertain future of Bitcoin and the questionable legality of running an unlicensed digital casino, we decided to sell the business and pursue more traditional ventures.

The primary focus of Tigerlily Labs (http://tigerli.ly) was codeStreak (www.codeStreak.com) - a 6-week, onsite Ruby on Rails program intended for individuals with little or no technical background. By the end of the program, students will have a great portfolio project, and enough technical skill to get a job as a junior developer.Additionally, Tigerlily is a small collective of freelancers. If you're looking for web development work, send a message! We focus on Ruby on Rails and node.js applications, but can build anything you can dream up.

I built most of the infrastructure and core systems of UniversityNow, including a Ruby on Rails classroom application, a node.js server to process inbound mail automatically, and several installs of wordpress for marketing sites. There's way too much to talk about in a little blurb, so ask me in person about my contributions!In addition, during my time at UniversityNow we had a contract with Pivotal Labs. I spent several months immersed in Pivotal culture, doing a deep dive into agile methodology, extreme programming, and development best practices.

I founded Trisse along with Tyler York. It was our own small flash-sale site, specializing in the artisan food and beverage niche. It was moderately successful, but soon after we got off the ground Gilt announced and launched Gilt Taste, which basically just blew us out of the water. The established Gilt brand lured many of our vendors, and although our vendors wanted to continue working with us, Gilt strong-armed them into exclusive contracts. In addition, it was just really difficult to compete with the massive marketing budget Gilt set up for Gilt Taste. All these things considered, we decided to close the company and end on a high note, rather than to fight what looked like it would be an impossible battle.I managed the business, handled the finances, and coded our website using Java/GWT, while Tyler led the marketing and product curation fronts.

I worked in mobile advertising. I'm primarily a server-side developer, but also frequently work on Android and iPhone SDKs.Google has an internal initiative called "20% time", which basically allows engineers to work on something outside of their core focus area one day a week. I took advantage of this freedom by getting involved with Google's EngEDU, a group that provides engineers with learning resources to help them be productive and grow their careers. In EngEDU, I donned the facilitator hat by teaching classes, leading group workshops, and giving interactive presentations. Not wanting to be limited to teaching engineers, I applied and was accepted to a similar organization-wide educational program where I contributed my skills as a member of gFaculty.

Transitioned AdMob systems onto Google infrastructure.Google's acquisition of AdMob was a bittersweet victory. It was great to work in a startup environment and to help make the company successful, but the shift to a corporate environment is tough. It's fantastic to have the resources and tools to build anything, but I really loved the challenge of working with limitations.

I redesigned and rebuilt AdWhirl (https://www.adwhirl.com/) to run as a distributed system on Amazon's cloud. The system has seen spikes of ~7,000 requests per second without breaking a sweat. I also rewrote the website from scratch, using an MVC design pattern. In addition, I created an Android client to use the service, as well as helped to develop the iPhone client.

A lot of people don't realize that Boeing does a lot of non-aircraft related defense contracts, and I was assigned to one of these (confidential) projects. The work itself was very interesting, but the large-company culture was not a good fit.

Working at CERT was fantastic, and I did a ton of awesome stuff there. Some highlights include:Building/extending a static analysis tool based on Compass/Rose's source-to-source compilation to check for security vulnerabilities in an automated fashion.Combing through the entire ISO C standard, and documenting all cases of undefined or implementation-defined behavior which would potentially contribute to a security vulnerability. You can view my work (I'd estimate that I contributed about a third of the project) at this wiki (https://www.securecoding.cert.org/confluence/display/seccode/CERT+C+Secure+Coding+Standard), which got published as this book (http://www.informit.com/store/product.aspx?isbn=0321563212).Contributing to this technical report on Ranged Integers for the C Programming Language (www.cert.org/archive/pdf/07tn027.pdf).
