• Utilized Tailwindcss with TypeScript and React to refactor the code base to employ better accessibility and reduce bugs left behindby contract engineers and to take advantage of server-side rendering, fetching, and other built-in features of NextJS.• Employed Firebase to authenticate users through 2-Factor Authentication using their email addresses, implemented socialauthentication through Google as well as authentication through credentials while encrypting the user’s password.• Led workshops to discuss and organize the common problems users faced on the site - these problems were prioritized in order tofind alignment within the team and to find solutions that could be turned into user-focused features that improved the product.

• Implemented Material UI with TypeScript and React in order to create a design system used to develop customized components to unify the site's theme.• Built GraphQL resolver functions using Prisma to handle PostgresQL processes as well as customized queries and mutations on the client side that worked with the Apollo Client to update the client’s cache and improve the efficiency of the site’s various pages.• Integrated Stripe API methods combined with NextJS’s Server Side Rendering on the site’s Payout page to accommodate various countries’ requirements for connecting bank accounts, Stripe’s own requirements, and StartPlaying’s requirements for bank accounts.• Utilized StorybookJS to document these components for easier cross-department workflows.• Utilized Ably to create a notification system and a chat application that would publish to the subscribed clients in real-time with new notifications and messages thereby creating a synchronized experience for the users communicating with each other on the site.• Utilized Terraform to implement database CPU utilization alarms on various AWS RDS database clusters by integrating AWS CloudWatch alarms with AWS SNS topics and queues which were triggered when CPU utilization went above certain thresholds. • Implemented a CI/CD pipeline using Github Actions in order to trigger Jest unit and integration tests, Cypress end to end tests, and to deploy a staging environment when merging to main which served as a test environment for non-technical team members.• StartPlayingGames is funded by Andreesen Horowitz (a16z) and was developed under the tech accelerator YCombinator.

• Utilized Typescript in the entire VS Code extension codebase to generate common type interfaces for fetched Gatsby plugin packages in order to more easily convey the inputs and outputs of each method and to create a foundation for extensibility.• Utilized the Jest.js testing framework for test driven development and employed mocking features to confirm Gatsby plugin packages were successfully being fetched and to confirm that core functionality was working as expected after incorporating each new feature.• Employed Travis CI in order to continuously integrate the code base by configuring a YAML file that ran scripts in an autonomous virtual machine environment to lint the entire codebase and run the Jest testing suite before every pull request was merged.• Implemented Webpack for easier maintainability and to decrease load times by configuring TypeScript compilation using ts-loaders on node modules in the source directory and using minification and uglification features to decrease bundled file size.• Created a plugin metadata parsing algorithm to fetch plugin packages and plugin information from the NPM API in tandem with the Got API and displayed data in VS Code via the TreeView API to generate a dynamic list of Gatsby plugins, starters, and themes. • This VS Code Extension was developed under the tech accelerator OS Labs ( opensourcelabs.io ) and is currently being maintained with tools and APIs from the GatsbyJS team with over 300+ installs on the Visual Studio Marketplace.

• Established Test Driven Development by implementing the Jest.js testing framework to create a testing suite in order to confirm the application’s core functionality was working everytime a new feature was incorporated into the application.• Incorporated the Supertest API into the Jest testing suite to generate tests for proposed features and to ensure that the server’s routers, controllers, and database were working as expected after each new feature was implemented.• Improved the data readability by visualizing the health of API URIs using D3 to generate a line graph based on the data from previous API calls and Material Design Bootstrap to create a pie chart using server status code data from a SQL database.

• Utilized Redux as a framework for organizing React state management, streamlining event handling, and minimizing prop drilling by dispatching action objects to the reducer when updating state and generating components that rely on various inputs.• Secured user data by utilizing Bcrypt to encrypt passwords before storing them in the PostgreSQL database and to decrypt passwords from the database when comparing them to the user input password thereby protecting users’ page and list data. • Incorporated React Router to establish static routes following a declarative model in order to minimize server calls within the single page application and to handle conditional routing depending whether the authentication step was successful.• Implemented Redux Thunk in order to generate asynchronous post requests within Redux action objects when posting user input data from the server and awaiting a response before sending actions to the reducer.

• Implemented React.js to create reusable calendar entry components rendered with dynamic user-generated content that utilized modular components and maximized maintainability by separating static and dynamic data and enforcing one-way data flow.• Established a Node.js/Express server to handle HTTP/API requests to the server and database by utilizing the middleware methods, creating routers and controllers to modularize backend requests with clear and distinct routes.• Implemented PostgreSQL database to have data stored and to be ACID compliant with strict schemas, enabling concurrent connections from multiple clients that can update list items and have changes reflected for the user’s page.
