## About

```text
At Wingify, I architected and built VWO's Feature Management & Experimentation SDKs for iOS and React Native, so enterprise clients could run feature flags and experiments in their mobile apps. I also designed a consistent public API and wrote integration documentation to make adoption simpler for client developers.

At Nintee, I joined the founding team and helped shape product direction from zero. I built and iterated on a habit-building app through experiments, analytics and user feedback, and prototyped LLM-powered features to explore where AI could improve the product.

After Nintee pivoted to education, I rapidly built and shipped product prototypes with React Native and Expo, validating ideas with real users. At Owltail, I led iOS development of its podcast player app, delivered features and App Store releases, and used app analytics to inform product decisions.

At Worksdelight, I delivered multiple client iOS projects and adopted React Native to extend the team's cross-platform offering. Earlier, at Apptunix, I built client apps in Swift and Objective-C and integrated third-party SDKs and backend APIs. I'm returning after a planned career break and seeking senior iOS or mobile SDK roles.
