Distributed Systems Developer in San Francisco, CA, United States

At Calm, I architected and led the transition from a Node.js monolith deployed on bare EC2 instances to containerized Go services running in Kubernetes. I developed the CI/CD workflow as well as many of the base libraries that were critical to the success of the transition.

At Calm, the growth of the company facilitated the need to become GDPR compliant.

I designed and led the implementation spanning all areas of our storage and infrastructure to meet the given requirements. I partnered with the legal team to create a "data map" providing clear guidance to the updates that must be carried out.

A hyper-local experience platform utilizing a hybrid of GPS and iBeacon information to pinpoint a user's location and use machine learning to deliver promotions and opportunities to the user.

For this, I negotiated an agreement with the largest casino operator on the Las Vegas strip to install hundreds of iBeacons throughout their properties. I personally developed the application in its entirety including the Objective-C library and plugin, a website to manage content and view user heatmaps, and a Node.js back end.

For the data store, I worked with the Bay Area company MemSQL to utilize a lightning-fast fully in-memory SQL database.

A Go-based service that communicated with multiple ad creative providers to source ad creatives. It blended the value of the creative with conversion probability (linear regression) to deliver the highest value creative to the user. This service is still the primary revenue generator for the company.

A full-stack product allowing customers to design creatives that would appear in a mobile application driving the user to make an in-app-purchase. This was hooked into the ad yield maximization platform to ensure the application developer displaying the ads received the maximal revenue possible.

The stack was as follows: front end (React), API layer (Go), database (Cassandra), and all deployed on Kubernetes.

A Unity engine, C# mobile game.

For this project, I worked as the front-end architect and project lead for all of the visual elements and components that were assembled into custom games through simple configurations. In this role, I built two parallel teams to utilize these components facilitating rapid development and iteration.

A C# mobile game developed in Unity Game Engine.

I was a founder of the company and the primary developer for this game. It was featured by Google multiple times and was downloaded over 1 million times. This game contained many complex implementations around time manipulation, object destruction, and animations.

An HTML5 game connected to a PHP back end.

I worked as a full-stack developer on this game for Zynga. The game was the first attempt for Zynga to utilize HTML5 for cross-platform gaming. The frameworks that were created were later used to accelerate the development of multiple successful games.
