Senior Mobile Engineer

Reliability First

Core engineering philosophy: assume failure, build for resilience, prove it in production.

Hard fact: software fails.

Murphy’s Law: “Anything that can go wrong will go wrong”

I design for failure

Ruthless testing. Guardrails. Defensive coding. Observability

Hard results:
💰 $1.5M+ losses prevented
⭐ 4.7 iOS rating
🛡️ 99.9% crash-free
📱 14+ years shipping production mobile apps
🌎 100% remote only

Scale evidence

Scale and delivery
Scale metrics:
📈 350k+ downloads
👥 70k+ MAU
📊 12M+ monthly screen views
React Native in → out
iOS + Android integration then full de‑integration
Push re‑architecture
backend + iOS + Android, 3 deployments, 0 incidents
App size 125MB → 28MB
reduced installs and updates for faster adoption

What I’m best at

React Native
iOS
  • React Native and iOS equal, then Android
  • Owning mobile products end-to-end: architecture, delivery, observability, reliability
  • Cross‑platform execution: React Native TypeScript plus deep iOS and Android native work
  • Stability and performance: startup time, slow path hunting, production incident prevention
  • CI/CD and automation: GitHub Actions, Fastlane, Appium, release hygiene
