Hello, Startup

I wrote a book! It's a "Hello, World" tutorial for building products, technologies, and teams in a startup environment. I based it off of my own experiences, as well as interviews with programmers from some of the most successful startups of the last decade, including Google, Facebook, LinkedIn, Twitter, GitHub, Stripe, Instagram, AdMob, Pinterest, and many others. If you're at all interested in startups, this book is for you.

Ping-Play: BigPipe Streaming for the Play Framework

An open source project that brings BigPipe streaming to the Play Framework.

Play Framework at LinkedIn

I led the project that brought the Play Framework to LinkedIn. Play is a modern web framework that combines the performance and reliability of Java and Scala, the power of reactive programming, and the productivity of full hot reload support.

LinkedIn Incubator

Launched a program at LinkedIn that allows any employee to come up with an idea, form a team, and present their projects to the execs. If approved, the team gets 3 months of dedicated time to bring the project to life.

LinkedIn Hackdays

Ran LinkedIn's internal and external hackday program. A hackday is an event where you get 24 hours to come up with ideas, form teams, and build rapid prototypes (hacks) as a proof of concept. I helped organize LinkedIn's public Intern Hackday, DevelopHer Hackday, and Veterans Hackday events, and built all the interactive information and registration pages.

LinkedIn Engineering Blog

I created the LinkedIn Engineering Blog as a place for LinkedIn developers to talk about their work and grew the site to many thousands of page views per day.

Resume Builder

I created and launched the Resume Builder as my first Hackday project at LinkedIn as a way to turn your LinkedIn profile into a nicely formatted resume.
