  • Reinforced 4 different teams, improved the platform performance and database queries, designed and launched dozens of features, and fixed many bugs, including whitehat-reported security vulnerabilities.
  • Scaled the dashboard to handle 40+ millions of credentials using OpenSearch and kept page load times below 3s. These pages weren’t loading at all for big clients.
  • Architected and documented an HTTP async API pattern to solve high-latency API requests due to the massive scale of some clients, creating and updating millions of credentials.
  • Automated the creation of testing data for staging environments, which drop and recreate the database and populate it with millions of records to replicate the production scale.
  • Relaunched coursefinder.io taking it from 250 visitors a week to over 3000 visitors a week.
