Engagement
What I take on in teams.
Feature delivery in the existing team: PR-based, Scrum or Kanban, CI integration.
Modernisation alongside day-to-day work: migrations, tests, release process.
Authentication and security: OIDC, FIDO, mTLS, session flows — including regulated environments.
Introducing SwiftUI and KMP with the team, not past it.
