Meteor JSON Simple Schema
Simple Schema is the most popular schema package for Meteor, which many other packages use to auto-generate forms and validate data before inserting it into MongoDB.

I wrote this open-source Meteor package to convert a JSON Schema object to a Simple Schema instance. It allows developers who spent time creating JSON schemas for other platforms to leverage their existing work in Meteor without recreating their schemas manually and maintaining them in both formats.


A platform to allow developers to share and collaborate on open-source schemas, including a back end as a service (BaaS) to store data using those schemas. Data owners can provide access to applications using OAuth or manual provisioning.

I was the author of the entire back-end platform—using Node.js and Mongoose—to dynamically generate APIs and allow developers to access/store user data within their applications.

I was also a major contributor to the developer portal written in Meteor and Node.js. The portal provides a way for developers to create and manage organizations, applications, models, and data maps and collaborate with other developers.

A Meteor package designed to convert a JSON schema to Simple Schema (the primary schema package for Meteor). This project was created to allow us to convert database-generated schemas into code on the fly so that we could use generated forms dynamically.

Racing Elements

I was responsible for developing both the iOS and Android versions of this application. I also managed the AWS hosting environment. Racing Elements was an immersive weather app highlighting professional photographs of Formula 1 races, cars, and drivers. We partnered with Paul Henri Cahier to source the images and used a weather service API to provide hourly and daily forecasts and current weather data.
