Core strengths

Focused spikes that make me effective on small teams.

Angular performance & DX

Signal-first patterns, tuned change detection, strict TS. Measure budgets and block regressions in CI.

  • pnpm/Corepack monorepos
  • DTOs + runtime validation
  • SSR/SSG when it helps

Electron pipelines & desktop UX

Hot-reload loops, safe IPC, filesystem watchers, SQLite tracking for large media sets.

  • Hash-based dedupe & batching
  • Worker isolation
  • Clear UI around complex workflows

iOS polish (Swift)

SwiftUI views, AV playback with offline caching, smooth navigation and empty states.

  • Background downloads & resume
  • Crash-free focus
  • Thoughtful animations when needed
