At TechMission Solutions Pvt. Ltd., I worked on the Church App / ParentPlus white-label mobile application for iOS and Android. I developed and maintained features with React Native, Expo, TypeScript, React Query, and REST APIs.

I built and maintained a custom video player with inline and fullscreen playback, subtitles, custom controls, and playback-state persistence. I also contributed to releases through EAS, TestFlight, App Store Connect, and Google Play Console, and to the ParentPlus Store Web project using Next.js.
