• Engineered React-based client-side rendered frontend to modularize component functionality, allow for easy code reusability, dynamically render data sent back by Graph QL calls to Apollo server and to maintain unidirectional data flow.• Utilized Apollo-Server to build spec-compliant Graph QL server in order to speed up development time by forgoing RESTful architecture and allow for universal compatibility.• Implemented Jest snapshot testing suite in conjunction with TravisCI for continuous integration testing to reduce development time in addition to preventing future codebase debugging.• Utilized React Router to create a dynamically rendered single-page application with multiple frontend URL endpoints, decreasing load times to create a more seamless user experience.• Built custom, application-specific Webpack configuration file, which was used to uglify and minify code for faster browser load times, to compile React JSX into browser-readable JavaScript, and to enable development server with hot-module reloading for faster code implementation.

• Implemented BCrypt authorization and login functionality to store hashed passwords in a PostgreSQL database for additional security in order to protect against rainbow table attacks.• Utilized Redux with Thunk to manage global state across multiple components without having to prop drill in accordance with the Observer design pattern, and to create actions that returned asynchronous functions with API calls to update the store while avoiding data mutation.• Built NoSQL database to user cart information in a JSON format without a strict schema.

• Built PostgreSQL relational database to store user data and persist user-specific search results across login sessions while maintaining ACID compliance and adhering to strict schemas.

• Leveraged Github OAuth login functionality to access publicly available user data to auto-generate user-profiles upon login, and to ensure security of user data by forgoing an internal database with sensitive user profile information.

• Built Node.js package to implement flexible, user-defined, global and route-specific functionality in Next.js in accordance with the middleware design pattern, intended to provide developers a more streamlined and lightweight way to make API calls in server-side-rendered applications.• Leveraged Javascript’s persistent lexically scoped reference data to properly manage middleware, and to persist updates made to request and response objects across multiple middleware function calls at user-defined routes.• Deployed Gatsby website built using a GraphQL data layer to retrieve data and dynamically generate static HTML files while foregoing a RESTful architecture for cleaner queries.• Utilized React Hooks in Next.js to provide functional components with state, modularizing functionality while allowing components to be dynamically updated and re-rendered.• Implemented Express server in pre-package testing application to handle incoming HTTP requests in accordance with the middleware design pattern, modularize back end logic with routers, and abstract functionality away from Node.js for faster code implementation.• Integrated Typescript to reduce runtime errors by implementing strict variable type enforcement.• Accelerated by OSLabs (opensourcelabs.io)

• Leveraged hardware and software interfaces for digital signal generation and processing.• Utilized audio compression, equalization and imaging to enhance instrument and vocal quality.• Conducted interviews for intern and assistant engineer candidates.
