How I work
Engineering approach
Principles I apply consistently across every product I build.
Reusable component architecture
I build UI from composable, well-typed components. This keeps codebases navigable, reduces duplication, and makes future changes predictable rather than risky.
Real-time & streaming interfaces
Hands-on with WebSockets, WebRTC, and streaming response UIs. Real-time features require careful state design to avoid flicker and inconsistency.
AI & voice API integration
Built production integrations with Google STT/TTS and AI streaming APIs. Voice and AI UIs need a clear feedback loop — loading, speaking, thinking states matter.
Performance-conscious development
I keep an eye on bundle size, rendering cost, and Core Web Vitals throughout. Performance improvements made early are cheaper than fixes post-launch.
Cross-platform development
Shipping on React Native alongside web. Shared state logic and design tokens reduce duplication while each surface gets appropriate UX treatment.
Maintainable code at scale
I write code with the next engineer in mind: consistent naming, clear boundaries, and debugging practices that make production issues faster to trace.
