Jan 2023 - Utilized Python to integrate big consumer data from flat files produced from various data sources - Developed Teradata DDLs for new tables to be used during file ingestion - Created ActiveBatch jobs for scheduling the execution of scripts based on business needs - Analyzed and updated SQL stored procedures and data sets to reflect weekly, monthly, quarterly and annual member and health plan updates - Employed Jenkins Pipeline for pushing code updates through development and production environments - Mentored newly hired engineers on development and data integration practices ### Software Developer @ Gaia Platform Jan 2021 – Jan 2022 | Bellevue, Washington, United States (Remote) ● Utilized TypeScript/JavaScript and React to spearhead the creation of an IntelliSense extension for Visual Studio Code, which includes features such as syntax highlighting, code completion, code snippets, and finding references for Gaia Platform’s declarative C++ syntax. ● Deployed and currently hosting IntelliSense VS Code Extension using Azure Devops Services. ● Applied GitHub Actions to dynamically publish VS Code extension to the Visual Studio Code Marketplace when changes are pushed into the main branch. ● Created an interactive terminal using Xterm.js(JavaScript)/HTML/CSS as well as performing other UI/UX improvements to the company’s Sandbox environment, which allows developers to test Gaia Platform’s framework through an interactive code editor and multiple web application scenarios. ● Crafted new server routes in a Python backend to serve different files to pre-populate code editor on the Sandbox front end. ● Launched an interactive tour using Bootstrap Tour to guide new users in a step-by-step tutorial of our Sandbox environment. ● Led demos in bi-weekly All Hands (company-wide) meetings to showcase new features and implement any feedback across the engineering teams. ● Practiced Agile Development in the form of two week sprints using Jira. ● Performed code reviews for other members of the Applications team to ensure code quality. ### API Watch (API Querying Tool) @ Open Source Jan 2021 – Jan 2021 | Remote ● Crafted an Express server to take advantage of the framework’s middleware design pattern that allowed me to strategically store cookies and sessions for persistent user login and to allow developers to add scalability while writing less code. ● Practiced Test Driven Development through the use of the Jest and Supertest Javascript testing libraries to test server endpoints and data flow between middleware for easier refactoring and increased readability of the codebase. ● Created various server-side algorithms using Javascript to query multiple categories of APIs, such as the Google Books and Goodreads book APIs, and send valid responses back to the user on the client side to eliminate the need for developers to parse through API’s for use in their applications. ● Utilized the bcrypt hashing function to secure user passwords and protect against potential hacking attacks. ### Job Beacon (Job Tracker) @ Open Source Jan 2021 – Jan 2021 | Remote ● Implemented React Hooks and Context API to have access to various job filters and attributes throughout the application for convenient state management throughout multiple layers of the component tree, therefore reducing complexity and resulting in a cleaner codebase. ● Configured SQL database with various relationships between jobs and their corresponding filters that are attributed to them to achieve maximum scalability and normalization to allow for easier table additions/updates and simpler schema migrations in the future. ● Constructed multiple components using React’s Material UI library for a tactile user interface, achieving the goal of a user friendly UI along with a component structure that is quick to build upon and easy to maintain as the application grows in complexity. ### Software Engineer @ UpNext Jan 2021 – Jan 2021 | Remote ● Developed a Visual Studio Code extension to create all of the necessary boilerplate for a SaaS (Software as a Service) application to reduce the time spent setting up their product and increasing their overall productivity. ● Defined TypeScript interfaces and custom data types to enforce static type error handling throughout the application which minimized errors, guaranteed scalability, and improved readability for future open source contributors. ● Utilized GraphQL typedefs and resolvers in tandem with a dual Express/Apollo Server which enables clients to request their own unique data specifications and reduce over/under fetching to save bandwidth and only provide data that the client needs. ● Incorporated Next Auth for user authentication and authorization, granting the user Oauth implementation of top providers including Facebook, Github, Twitter, and Google for increased security for the end user. ● Integrated React with React Hooks to build out home, signup, and login pages to give the user flexibility to build a variety of platforms with easy re-use of stateful logic and the elimination of superfluous class components for minification optimization. ● Applied Next.js to incorporate a hybrid of SSG (static site generation) and SSR (server-side rendering) to allow users to pre-render pages at either build or request time so they can serve their dynamic and static elements efficiently. ● Employed the Next/Link and Next/Router libraries to handle client-side transitions between routes, allowing for short page load time and responsive websites to improve overall user experience when navigating throughout the application. ● Leveraged Stripe API to allow developers to accept payments and manage subscription billing plans, giving the developer the ability to monetize their products and ensure security of their users’ funds. ● Product developed under the tech accelerator OS Labs (opensourcelabs.io). ## Education ### Bachelor's degree UC Irvine Jan 2013 –
