Summary

Software Engineer III at FullBloom / CharacterStrong, building products that schools and educators use every day. I do my best work before the first commit: a clear spec, one diagram everyone agrees on, and tickets small enough to finish. B.S. in Economics from UT Austin; M.S. in Computer Science at Georgia Tech in progress.

Experience

May 2023 – Present

Software Engineer III · FullBloom / CharacterStrong

  • Designed a modernized authentication system (credentials, SSO, SAML, rostering) with unified MFA and session handling; wrote the sequence, flow and entity diagrams and the Jira initiative to lead the build.
  • Led multi-organization user management across the platform, so administrators can add, remove, restore and manage users across entire districts.
  • Made the rostering pipeline more scalable and reliable with distributed processing and locking, and fixed import and sync issues.
  • Built an AWS Step Functions ETL pipeline for Clever, SFTP and ClassLink that syncs rosters nightly for hundreds of districts, processing millions of user and class records.
  • Secured 26 legacy endpoints with user-based middleware, separate business-logic and data-access layers, and standard request validation.
  • As an intern, built 23 pages and 88 components from Figma designs in React and TypeScript, and led the upgrade from Mantine v5 to v6.
