Lunit

What I did

  • Built the oncology data management platform from scratch, designing the domain model and database schema for pathology assets; now used across three teams.
  • Maintained the slide annotation system that produces the labeled training data behind Lunit's oncology models, supporting more than a million annotations across hundreds of thousands of slides.
  • Improved observability by creating Grafana dashboards, reducing time to diagnose production issues.
  • Authored technical plans behind several projects, including architecture decisions, trade-offs, discarded alternatives, database modeling, maintainability, and implementation plans.
  • Translated ambiguous product requirements into implementation plans by reviewing PRDs and UI designs, and working directly with PMs, end users, designers, frontend engineers, and leadership.
  • Worked together with the DevOps team to migrate infrastructure and run releases.
