about

While I loved my time as a software engineer, I quickly decided it would not be my whole career. I've always wanted to work in public interest over corporate, but I still wanted to use my knowledge about technology. I believe law is the best field for that intersection. So, I now am a student at NYU Law and recipient of the Desmarais Law and Technology Scholarship. At school, I'm a web designer and student fellow for the Privacy Research Group, president of Rights over Tech, and an intake manager for the Suspension Representation Project. I am also a staff editor on the Journal of Law and Public Policy.

Finally, I conducted legal research relating to insurance and personal jurisdiction.

ragdoll run

May 2020 - Active Development

In the time in between my graduation and start at Microsoft, I decided to fulfill my childhood dream of publishing an app. In about a month, I developed Ragdoll Run, now available on the App Store.

I built it using Apple's SpriteKit framework in addition to StoreKit, CloudKit, and Google AdMob. It fully supports iPhone, iPad, and iMessage. 50% of revenue from in-app purchases and ads is donated to non-profits.

I was a Software Engineering Intern on Intune's mobile app management (MAM) team for Android. They develop an SDK that allows IT pros to make tightly managed apps. I made an example app demonstrating how to use this SDK called Taskr. Taskr is open source and available on GitHub.

I finished this project in half of my internship, so I spent the rest of the time fixing bugs on sprints with my team. I specifically focused on bugs that had arisen from multi-process Android apps.

equisat

September 2016 - May 2020

Brown Space Engineering is are dedicated to making space more accessible for people of all backgrounds. Following our schematics, anyone can make a satellite for only $3,776. Successfully deployed on July 13th, 2018, EQUiSat is the first satellite to test LiFePO batteries in space and its four LEDs are visible by the naked eye. I worked on organizing satellite operations using FreeRTOS and optimizing data transmission, especially error packaging.

I became project manager and co-president in 2018, so in addition to coordinating satellite operations and managing our over 75 members, I led the design of our next CubeSat, PVDX. I was responsible for communication with NASA, the University, and any other external entity.

wikispeedia

March - May 2017

The Wikipedia game is an old standby for bored teens, but it's rarely done right. For my final project for CS 32 at Brown, my group and I decided to perfect this age-old game. I worked on the user experience, including lobby experience, site-wide design, and graphic design. I also set up hosting so anyone can play online.

Want to play the game yourself? You can play here! Since it is hosted on Heroku's free tier, please give the app a few seconds to start up. You can view the code on our project GitHub repo.

this-site

Work in progress

Since mid 2016, I've been continuously redesigning jleiken.com, this site. In this most recent iteration, I decided to mimic the experience of using a terminal. Nearly every semester in college I found myself writing a REPL, so I have very strong ideas about what I like and what I don't. Drawing on that experience, combined with my modern Javascript experience at Amazon, I decided to write this website in pure ES, no jQuery involved. The static version, for mobile and visitors unfamiliar with terminals, serves as a template for the REPL version. This means that the Javascript can pull from the HTML - there are very few strings that contain HTML code.

The site is hosted on Github Pages and uses Jekyll for Sass. If you're interested in how I wrote this site, you can view the source code on Github. The REPL is defined in js/repl.js and run from js/index.js.
