Profile bio

About Jeremy J.

"To connect people to their passions, communities, and the world's knowledge." -- The first time I heard this former corporate mission statement, I 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 to do good. I love developing tools and experiences that help people to connect with their communities and loved ones in better and richer ways. I am passionate about teaching others and sharing my own knowledge and experience with my coworkers, colleagues, and contacts. I excel at creating out of the box ideas to solve challenging problems. Through all of these things, I impact my workplace, my personal life, and subsequently on the world as a whole.My experience ranges from being a lone engineer working in isolation on skunkworks projects to being the chief architect managing a large team of engineers. To highlight some of those achievements: I developed a site with ~700k page views/day in 2002; I also architected the PHP framework / coded a large chunk of a project with hundreds of millions of DAUs; and I further architected / developed another project collecting billions of data points from devices deployed in major retail stores and malls across the globe. I am confident in being able to handle a project of virtually any scale and can easily help deliver high performance results. I embody the term "full stack" developer to its fullest, covering from designing and building hardware, to systems work including kernel tuning / low level network stack / automation, up through scaling backend applications and services, and finally to user experience work on the web, TVs, and mobile. I have a proven track record of managing teams of various sizes and building upon the abilities of the team to lead them to success. I can equally handle teams of junior and senior developers, coaching and mentoring them to be the best they can be.

Listed skills include Php, Python, Ruby, C, and 45 others.

Developer Advocate

Sunnyvale, Ca, Us

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.
