React Native / Web Developer

White Oak Music Hall • Freelance

Jan 2026 - Mar 2026 • 2 mos

Re-contracted to build on the previous festival app, migrating from state-managed tabs to full page routing for a cleaner navigation architecture. Improved UX for the local food and drinks map—more fluid scrolling and snappier tap response on the overlaid business carousel. Drastically enhanced the schedule sharing feature to dynamically render image cards based on the number of bands selected, eliminating single-band card clutter and producing share-worthy visuals for social media. Rebuilt the CMS from the ground up—fest staff can now manage everything: lineup, show dates, stages, vendor list, local businesses, and external/social links, plus a new overview page displaying a live snapshot of all app data. Expanded platform support from iOS-only to full iOS and Android deployment.

Front End React Native Developer

Mognito • Freelance

May 2025 - Dec 2025 • 7 mos

Developed reusable UI templates for various user activities and menus, following figma designs to a ‘T’. Debugged and enhanced auth flow with supabase by incorporating proper UI error messaging, making sure to explain the issue to the user. Cleaned up and enhanced existing UI components and improved reusability and consistency by following the single-use principle which reduced clutter and made code much more readable. Contributed to MVP scoping and goal-setting; collaborating with UI designer, back end engineers, and CEO to add enhancements like haptic feedback.

React Native / Web Developer

White Oak Music Hall • Freelance

Oct 2024 - Mar 2025 • 5 mos

Contracted to design and develop a React Native iOS app for 1500+ users and a web-based CMS for managing real-time news for a music festival, integrating Firebase (Firestore & Auth) for storing and retrieving bands, set times, news feed, and selected local shops/restaurants. Built a one-tap schedule-building feature, incorporated google maps API, leveraged regex text formatting, and led testing and deployment—all while rapidly mastering TypeScript/React Native/Expo.
