Genetic Baseball Lineup Optimization

Built a web-based optimizer for baseball lineups. It uses Rust and WebAssembly, dynamic programming, Web Workers, and genetic algorithms. By leveraging these advanced techniques, the optimizer efficiently searched through an extensive search space (typically nine) to identify the most optimal lineup configurations.

Jornaya Client Portal

Spearheaded the development of the comprehensive onboarding and management application for Jornaya's industry-leading data products. This involved working on the application's back and front end. The front end was built using Elm, while WebAssembly Workers running in Rust were utilized for efficient file processing. By implementing this solution, we successfully transformed the client onboarding process from taking weeks to mere minutes, seamlessly integrating it into the data platform.


Meta's (formerly Facebook) Creator Monetization play for the journalism space is designed to allow journalists to monetize their audiences without being beheld by their advertisers. It enables journalists to create content streams with premium subscriptions, set perks, discounts, and paywalls, and set advertising distribution and outreach.

I led the Creator Monetization side of the team, building the tools for creators to set up monetization, subscription plans, benefits, discounts, payments, payouts, and perks.

SHERLOC Police Intelligence Database

I built a web application to allow police departments to do data analysis on their existing public service data. It brought the power of machine learning to allow police departments to optimize their budget spend and patrol routes.
I provided heat-map reports, cyclic pattern reports, and seasonality reports. I also implemented an advanced search to allow similar cases to find relevant suspects and a network graph analysis to help combat gang activity.

Dandy Design and Manufacturing Router

I led the team responsible for routing each of Dandy's 3-5000 orders per day to the best-matched designer based on job requirements and then to the most cost-effective manufacturer based on job cost, location, and schedule availability.

The router was written in Node.js and TypeScript on top of Kubernetes on GCP. I also used BullMQ queues to allow efficient scaling and prevent bottlenecks on complex scheduling calculations.

Family Health Center Patient Operating System

I built a patient management system with a patient portal for a local holistic healing center. I allowed the doctors to do data analysis on their different treatment packages to measure effectiveness for different types of cases. It allowed patients to access their care packages, as well as history of test results and treatment courses, contact the doctors, and schedule appointments.
I maintained HIPAA compliance and encrypted all of the data at rest, as well as allowed for anonymized and blinded reports to allow submissions of treatment packages for recommendation to the FDA.
