Contract via Insight GlobalProject Description:Rewriting Coda application from Angular JS to React JS using hooks. Coda is an intrinsic dashboard application used by Walt Disney Animation Studios. Its primary function is to provide real-time progress tracking of animation rendering. Once animations are dispatched to Disney's high-performance supercomputers for rendering, Coda becomes an essential tool for internal designers and artists, enabling them to monitor rendering progress, anticipate completion times, and detect potential issues.Front-end Development:- Utilized JavaScript (ES6) to create efficient and contemporary UI components.- Expertly incorporated the ReactJS library, emphasizing a component-based architecture for reusability and maintainability.- Employed React Hooks, streamlining state management and lifecycle events within functional components.- Enhanced code reliability and predictability by integrating TypeScript. Back-end Development:- Designed and implemented robust endpoints using the Java Spring Boot framework, ensuring scalability and high availability.- Integrated ElasticSearch for real-time data indexing and complex search capabilities, optimizing the system's responsiveness when retrieving and rendering progress data.Deployment:- Managed application deployments on Amazon Web Services (AWS), leveraging its cloud capabilities to ensure seamless release cycles and high availability.Migration and Enhancement:- Spearheaded the migration of the Coda application from AngularJS to ReactJS. This strategic decision was made to leverage React's virtual DOM, enhancing the dashboard's performance, especially for real-time data updates.Technology Stack:Front-end with Javascript (ES6) with framework ReactJS w/ TypeScript & NextJS.Back-end worked with Java framework SpringBoot & NodeJS. Database modifications using PostgreSQL.Deployment AWS.

Contract via Austin FraserProject Description:New software that would replace 3 outsourced applications that were replicated and merged into in-house software for daily traders. Tasked with creating the front-end of an internal software designed to replace outdated trading platforms. As the sole front-end developer in a team that included two back-end developers, I took the initiative to create the UI/UX from the ground up. Emphasized modularity in the front-end design, crafting reusable components to ensure that future software developments could leverage the work, reducing time-to-market for subsequent projects, and ensuring consistent user experiences. Worked in an interdisciplinary team, liaising between design, back-end development, and stakeholders to deliver a cohesive and efficient software solution that catered to the specific needs of the trading department.Designed and implemented robust user interfaces using ReactJS, ensuring dynamic and responsive UI components.Integrated TypeScript with React, leveraging its static typing feature to catch errors early, making the code more predictable and easier to debug.Adopted React’s component-based architecture, which enabled the isolation of functionalities, promoting code reusability and easier testing.Collaborated closely with two back-end developers proficient in Java Spring Boot and Express NodeJS.Ensured seamless integration between the front-end and back-end by setting up consistent API contracts and conducting integration tests. Employed agile methodologies for iterative development and to accommodate changing requirements while maintaining robustness in the application's back-end.Technology Stack:Front-end with Javascript (ES6) with framework ReactJS w/ TypeScript.Back-end worked with Java framework SpringBoot & NodeJS.

Fulltime EmployeeProject Description:Created and developed in-house global scalable software such as Supply Collaboration apps that would track shipments from supplier to warehouse and communication between them included upload functionalities and generated reports for General Motors executives. Helped create CPC which gave any part that General Motors has and will have in the future a unique global identifying number called CPC composed of 16-digits, the application was made to have a global standard. Many regions where General Motors operates around the world had different ways to “uniquely” identify a part. It was difficult to identify one part in one region with another region part even though it might be the same part, because there was no global standard of identification set in place until we created CPC.
