User journeys, not just screens
Onboarding, activation, core loops, and retention-oriented UX, owning the problem, implementation, and follow-up quality.
Engineering with release discipline
Modern concurrency, modular architecture, performance profiling, and reliable release workflows for consumer apps.
Ship fast, measure impact
Crash analytics, Instruments, funnel thinking, and tight founder/engineering collaboration in small teams.
LLM tools with engineering judgment
LLMs speed up research, scaffolding, and iteration, with senior review so nothing ships with security gaps or rework that non-technical stakeholders cannot catch.
