Release infrastructure, maintenance, and features for shipped apps →

I rebuilt Lumosity's release pipeline from 18 months per title to 3. The CI/CD work behind reliable releases is some of my favorite work — and it shows up directly in your reviews.

  • CI/CD pipelines and release infrastructure (Fastlane, GitHub Actions, Jenkins)
  • SDK and platform target updates
  • Bug triage, stability, and crash reduction
  • Performance, rendering, and memory work
  • App Review and compliance fixes
  • New features against existing codebases
