Engineering Leader

As a mobile engineering leader at Route, I successfully developed and implemented an OKR-based roadmap for a consumer-focused organization, covering 8 engineering teams. My efforts resulted in a more efficient and productive team culture that aligned with the company's vision and priorities, leading to a 1.5x increase in weekly shipping cycles and balanced delivery across mobile, web, data, QA, and fullstack teams.

I also played a key role in the professional development of the employees across the company, providing guidance and support through educational programs to help grow Route's leaders. This included promoting several engineers to lead roles and leads to management positions. Additionally, I led performance reviews and provided calibration feedback, and advised on having a shared understanding of developer productivity through the use of SPACE and DORA metrics for a team of 50 engineers.

I also contributed to the leadership hiring playbook providing input on questions and exercises, collaborating with HR in helping shape the company's approach to identifying, evaluating, and onboarding new leaders, with the goal of finding the best fit for the organization's needs.

Mix began as a co-op product between Garrett Camp (founder of Uber) myself, and a third cofounder. Together we collaborated to create something that mixed each of our interests and backgrounds (pun intended, of course). With my experience in developing social networks, and Garretts profound knowledge in content discovery (StumbleUpon), we created an idea that allows users to discover, collect, and share content with like-minded friends. Mix remains in the AppStore today with over 30,000 creators.

Medium, Inc
Founding Full Stack Engineer

When I followed Ev Williams from Twitter over to the Obvious Corp, the idea of Medium didn't exist yet. So while ideations of potential directions percolated among the team, my initial focus was on building web platform tooling. Ultimately I co-created a Node MVC server framework from which Medium would eventually be built upon.

Six months prior to the Medium launch, my focus switched to becoming the sole creator of the frontend writing experience, "The Medium Editor," which went on to become a wildly favored writing experience according to many well known writers in the industry read by over 100M people world-wide.

Twitter, Inc
Frontend Lead Engineer

As an early employee (#30) at Twitter, my role was to create the first official Twitter frontend widget platform for 3rd party developers.

This initially included the embedable timeline widgets, which became responsible for the company seeing a 30% uptick in search traffic the following quarter after launch

Later I went on to co-create the Twitter JavaScript API (known as @Anywhere), a 1:1 mapping of API available within a browser effort led to other embedable components that I developed such as the tweet and follow buttons.

Because of this new tooling, in 2010 I joined a small task force team [war room style] to create a new twitter.com redsign and rearchitecture atop of our newly created JavaScript API. This also included new rich interfaces and experiences (not seen before on the twitter platform) such as embedable media, infinite scrolling, user autocomplete, even hover cards (^_^)/

Much of this work ultimately led to the inspiration and creation of many popular open sourced libraries such as Qwery (a CSS selector engine), Reqwest (http ajax client), Morpheus (high performance browser animator), script.js (dependency manager), and many more!

Design Engineer, Educator

My principle role at Google was to work between the User Experience Team and Software Engineers as Google's lead prototyper and web developer within the Gmail org. This involved creating exploratory rich UIs used for RITE studies and then graduate the usable pieces into Google's main UI library (Closure).

Midway through my tenure at Google I co-created a full day web development hands-on course called HTML, CSS, and JavaScript from the ground up through the Google Engineering Education program. Designed for newcomers (Product Managers or Designers) and experienced Software Engineers alike.

Ultimately this course went on to become Google's most popular (by attendance) of all time within the Google Eng Education program.

JavaScript Design Patterns

JavaScript is a hugely popular language for adding dynamic functionality to web pages, and it is possible to use design patterns within JavaScript to further improve your code - they can improve efficiency, cut down on repetition, and provide useful frameworks to build code on top of. This book (the only one available covering JavaScript design patterns thoroughly) gives web developers all they know to start using design patterns in their JavaScripting, including several real world examples for them to learn from.

In 2009, I began a “365 project,” the goal of which is to shoot and share one picture per day for a year. I shared both the final image and the behind-the-scenes setup shot for that image, allowing the viewer to see how the shot was arranged. I also included information about exposure, flash power, distance, and light modifiers. The project was a huge hit that attracted thousands of followers
