The most amazing...

...thing I’ve coded is a linear programming financial portfolio optimizer. It generated better answers than the replaced system and ran 200 times faster.

  • Chemowave (Development)

    Chemowave is a chemotherapy recovery app that reminded users to take medications and track their health. I revamped it to use interactive graphs and charts so that patients could correlate behavioral patterns with their overall recovery. I used Swift 3, Core Graphics, and the Charts library.

  • PhoneFit (Development)

    I created an iOS app with a serverless AWS back-end that allowed personal trainers to create, save, and share video-based workout routines with clients. The full stack includes a frontend in Swift 3 and a back-end in Node.js utilizing Cognito, API Gateway, Lambda, DynamoDB, and CloudSearch.

  • Portfolio Rebalancing Engine (Development)

    I led the effort to build the financial portfolio rebalancing engine that Vanguard financial advisors use. It was a number-crunching program that took an input portfolio and gave recommended changes based off of thousands of linear equations and constraints. The program was written in Java with a Cucumber automated test suite to verify regression test cases.
