-Developed a Chrome Extension for React developers to fill a gap in managing the flow of data requests and occurrences of data “waterfalls”, by providing the developer a visualization tool mapping out all requests throughout the application. -Used Babel as library to build our parser function, as it made for clear traversal of the code and allowed us full control over what was extracted from the AST. -Utilized Jest unit tests to ensure effectiveness of our parser and fiberwalker functions, along with Storybook snapshots to test if our mock React app integrated correctly. -Traversed React Fiber Tree to deep dive into the heart of a React application and map out the entire structure for integration with our visualization tool. -Implemented Air BnB’s visx technology to build visualization tree object, written in TypeScript for debugging ease and type reliability. -Refactored parser function to be written in TypeScript for type precision and debugging ease. -Developed under OS Labs group.

-Grocery shopping application built for both web and mobile use, designed for individuals or families that helps to manage their current inventory and a running grocery shopping list. -Built Redux store with the purpose of storing application state in one global spot, for ease of retrieval in any component throughout React application, and improved overall readability of the code once initialized correctly. -Initialized a SQL database to have relational data stored and accessible to be ACID compliant with strict schemas, enabling concurrent connections from multiple clients that can update state and have changes reflected for other users. -Built application with Webpack for future scale, maintainability and faster load times by writing configuration to utilize hot module reloading, ES6+ transpilation for developer packages, and using minification and uglification features to decrease bundle size.

-Leveraged a SQL-like query language (called Q) to query data from kdb+ data management system in order to compile financial information at a very high speed. -Utilized Pandas library to manipulate data returned from kdb and then passed information along to the Derivatives Trading Team for them to make more informed trading decisions.
