I'm a mobile engineer at Popl who builds tools that make complex systems easier to understand, test, and operate.
My work spans mobile infrastructure, state tooling, open-source libraries, and agent-native engineering workflows. The recurring goal is the same: expose the real contract, make it testable, and give people a small interface they can trust.
I work on Popl's React Native application across product and engineering boundaries. My work includes owning a ground-up navigation rearchitecture, resolving problems at their underlying integration points, and applying agentic workflows to shorten debugging, testing, and delivery loops.
The details of that codebase are private; the public projects below show how I approach similar classes of complexity.
| Project | What it makes easier |
|---|---|
expo-targets |
Building native extensions and targets—widgets, App Clips, share extensions, and more—inside Expo projects |
zustand-expo-devtools |
Inspecting Zustand state, actions, and history through Expo DevTools |
zustand-getters |
Expressing reactive derived state with ordinary JavaScript getters |
skeleton |
Keeping the documentation, skills, and source-of-truth contracts agents depend on internally consistent |
toolbox |
Reusing engineering workflows such as Council, Grill, and Refactor Companion across coding agents |
react-native-progressive-blur-view |
Adding a focused progressive-blur primitive to React Native interfaces |
Mobile platforms, state systems, and agent workflows all hide meaningful complexity. I prefer to name that complexity and give it one clear owner instead of accumulating symptom-level fixes. The result should be explicit and testable internally, but small and unsurprising for the person using it. That principle guides both my work at Popl and the tools I build independently.

These are public implementation reports, not company endorsements or production claims. The open-source adoption ledger records the dated metrics, integrations, sources, and limitations behind each claim.
I studied Computer Science and Psychology at Santa Clara University and graduated summa cum laude. I like learning difficult systems, understanding the people operating them, and distilling what I learn into tools and explanations other people can use.
