SvelteSlicer | Chrome extension debugging tool for Svelte app | 2021~

*Designed and developed real-time, bi-directional communication between web clients and servers with socket.io.

* Utilized non-relational data base MongoDB to handle and store clients’ data and communication history among multiple users for low latency and faster performance.

* Improved upon existing REST endpoints and middleware using Express in Node.js in order to execute functionality for group chats by efficiently verifying user login and group chat status while gathering group chat metadata using document data model, facilitating real-time interaction and communication between users.

* Utilized PostgreSQL database to allow relational data storage and access to be ACID compliant with strict schemas, enabling concurrent connections by users to facilitate goal modifications and status updates in a higher security layer

*Established controllers from services to orchestrate requests and responses making code more reusable and easier to refactor and test use.

* Formulated Node.js, Express middleware to modularize server-side code, handle and modify HTTP requests in an efficient manner with a discernible chain of responsibility, enhancing code readability and easy debugging makes it more efficient than with vanilla Node.js

*Designed user-facing feature video upload and management application by React, nonrelational database express.js and CSS.

*Implement React Hooks to write cleaner code by incorporating states changes to improve state flow and reducing DOM re-renders by mapping variables in the fewest amount of components and also maintain stateful logic between components to make it easier to refactor, reuse when the application grows.

* Utilized Express/Node to architect a back-end structure comprised of customized modular middleware to handle asynchronous data-flow between use and server efficiently
