Music Festival and Events Updates Web Scraper-Built a React Native Mobile App with Expo CLI due to its modular nature, ease of rapid prototyping and synchronized data flow for efficiency and cross device compatibility on mobile apps-Leveraged a proprietary data scraper to asynchronously aggregate data from legacy codebase and various custom APIs based on a user’s geolocation

Utilized React’s virtual DOM and conditional rendering to create a performant dev tool panel to dynamically display GraphQL request/response, server side GraphQL schema, and Apollo Client side in-memory cache.• Leveraged React Hooks to organize component logic and state into reusable encapsulated units, ensure explicit data flow, composition inside component, enforced component purity and improved rendering speed.• Incorporated TypeScript to catch errors at compile time, referenced consistent structural implementation of design interfaces to enforce expected shapes of function parameters, and greatly improved code maintainability.• Dynamically detected GraphQL client side requests and fetched introspection query to endpoints to provide users access to available fields and types in the schema to facilitate query validation.• Generated an interactive D3 component tree by implementing a recursive algorithm to dynamically traverse, flatten, and transform GraphQL query response data into D3 compatible data format.• Optimized Webpack configuration for code splitting, minification, and uglification to improve load time and performance, ,facilitate the development process by leveraging hot reloading with React Dev server and provide a seamless UX to users.• Applied TDD and CI/CD with Jest, Enzyme and Travis CI by automating the process of unit and integration testing to progressively verify component performance, expedite feature integration, and re-enforce codebase stability.• Accelerated at OS Labs.
