Hi, I'm Zack.

Email me · (917) 267-9225 · In Brooklyn

I have 10+ years experience writing code for server, web, and iOS. I’ve also been a manager, bartended a little bit, and love to travel. If you’d like to work with me or just grab coffee to chat, say hi.

Here’s where else you can find me on the internet

Freelance Work

"Zack Sheppard, LLC."

Since August 2018, I've been available for work as a freelance engineer, manager, consultant, and mentor. See below if you'd like to hire me.

August 2018 - Present


I worked for 7 years at Foursquare. Starting as a new grad hire on the API/Server team, then moving to the web team, and finally landing on the iOS team, I would move wherever there was a need for someone to learn a stack and execute quickly. Once I settled into my role on the iOS team, I rose to be the platform lead in the company, then to manage the Swarm mobile app team, and finally to manage the app engineers for all of our consumer apps.

June 2011 - June 2018


Google and VoodooVox, Inc.

My first summer of college, I interned at a small startup called VoodooVox (now defunct). Here I wrote an app for the iOS store ready for Day 1. The next two summers, I interned at Google on their search indexer team and then on their Sheets team. If you've ever used "Paint Format" in Google Sheets, that was my project.

2008 - 2011


Williams College and Columbia University

I started learning programming and computer science while in high school, taking classes at Williams College. After high school, I attended Columbia University in New York City. There, I finished a BA in computer science (while also acting in a lot of theatre).


My Present Focus

These days, I'm working as a freelancer on an hourly or project basis. So, if you have need for someone with my experience, send me an email! Let's talk about how I can help, whether you need a manager to help train your team and build your company culture, or an engineer to build your apps, APIs, and websites, or even bartender to help you pick the right bottle of scotch or champagne to celebrate a special launch! I am there to help build things and help your team celebrate, enjoy, and take pride in their achievements.

Programming Languages & Tools

I know Swift, Objective-C, HTML, CSS, and Javascript. I have experience integrating front-ends with all common server backends (except Ruby, sorry), as well as experience deploying code with Docker, Firebase, and AWS.
