“To connect people to their passions, communities, and the world’s knowledge.” -- While I didn’t write this phrase, since hearing it for the first time I have realized that this is the best way to describe my own personal objective in life. I love helping people to find things they are passionate about and helping them grow and leverage those passions. I love building/coding tools and experiences which help people to connect with their communities and loved ones in better and more rich ways. I love teaching others new things and sharing my own knowledge and experience with everyone possible. It’s through these things, as well as connecting people with others in various ways to make things happen, and enabling things otherwise not possible, that I feel I can have the biggest impact in the workplace, my personal life, and subsequently on the world as a whole.

My experience ranges from a project I alone developed averaging about 500-700k pageviews/day (at the time) all the way to architecting the PHP framework and coding a large chunk of a project with 100s millions/day. I am confident in being able to handle a project of virtually any scale and can easily help deliver high performance results.

Specialties:Programming Languages: PHP, Javascript, Ruby, Adobe Flex 2 & 3 (including experience w/ Adobe AIR), Actionscript 3 (and to a much lesser extent AS2), Python, C, C++, Perl, HaXe

General: Photography (I used to handle a large chunk of Yahoo!s PR headshots as well as many corporate events), Evangelism (just look at what I did to my car,, while at Yahoo! for example), and Community / Developer outreach efforts

Site Reliability Engineer

– Present (10 months)New York, NY

Placeholder for position

Product Engineer

(1 year 8 months)New York, NY

Will fill this out more later, just wanted the position listed. :)

Developer Advocate

(1 year 3 months)Mountain View, CA

As a developer advocate at LinkedIn, I am dedicated to helping our internal and external developers successfully create applications using the LinkedIn API platform.

In this role, I interact with our developers via email, on the phone, in person, and on our forums. I provide pointers to documentation, triage bugs, offer code examples, and explain our system to keep people from getting stuck while integrating our platform into their offerings.

I speak at conferences and meetups to educate and engage developers with the LinkedIn API and to provide a broad overview of the many things LinkedIn is currently doing. My talks are generally an overview of our platform with hands on code samples showing real functionality (even including a little live coding if I am feeling adventurous). I try to demonstrate real world functionality, rather than generic "Hello World" type tutorials, so they provide the most impact possible to interested developers.

Documentation is a critical facet of developer support. I write and update documentation on our Developer Portal, including tutorials, reference materials and example code. I also was actively involved in the move of our developer portal from Jive to Drupal, including the writing of several custom Drupal modules and extensive configuration and debugging work.

One very important aspect of developer relations is to facilitate communication between the developer community and our product teams. Our team listens to the feedback and wishlists from our developers and communicates that to the product teams - and I also participate in design and development discussions to ensure the quality of new features and improvements.

At the end of the day, I am not successful unless our partners are successful, so I work with our LinkedIn partners as much as possible to help them develop excellent LinkedIn applications using our API.
