AmeriCamp connects participants with summer camps across the United States. The mobile application manages the complete applicant journey—signup, profile creation, interviews, document uploads, stage-based payments, visa processing, and pre-departure logistics—through a guided, gamified experience with progress dashboards, badges, and real-time notifications. I led front-end development in React Native against a Ruby on Rails backend, turning a complex multi-step manual process into a transparent, intuitive flow across Android and iOS.
I built a resilient multi-stage onboarding system on Redux with versioned persisted state and per-stage snapshots, so applicants never lose progress. Payments run through a server-managed Stripe integration with 3DS flows, webhook reconciliation, and OCR card scanning that tokenizes immediately and discards images. Documents, signatures, and camera uploads move through presigned S3 URLs with client-side compression, chunked resumable transfers, and background tasks. Adaptive HLS video streaming with CDN caching keeps orientation content smooth on unstable networks.
Redux with thunk/observable async flows, versioned persisted state, and migration functions—eliminating race conditions and corrupt-state desync across sessions.
Server-only tokenization keeps the app out of PCI scope; 3DS/SCA flows, webhook retries, and a reconciliation job keep every stage fee accounted for.
Native signature canvas exported at controlled resolution, plus camera and document uploads with compression, chunked resumable transfers, and progress tracking.
Card scanning with immediate in-memory tokenization—images are never stored, with manual entry as a privacy-safe fallback.
HLS playback with CDN caching, pre-buffering, and low-quality fallbacks for reliable viewing on slow networks.
A React Native app connecting applicants to U.S. summer camps, guiding them through signup, interviews, payments, and visa processing. Gamified dashboards, badges, and real-time notifications turn a complex manual journey into a smooth cross-platform experience.
