SW Engineer 2 @ My team is mainly focusing on improving the way how Quickbooks serves help content to help the user understand how to make the best use of Quickbooks. I am working on both the Quickbooks support web site, Quickbooks in-product help system and the related back end services. 1. Fetch application data from back end services and render dynamic content on the font end web page using Knockout JS, JSON, and javascript. 2. Worked with infrastructure engineers to troubleshoot web applications across multiple tiers (front end application, back end services and databases), identified and fixed urgent customer facing issues. 3. Fetch application data from community web app and transform the data format in the help content search service to accommodate the data format change after community app migration. 4. Redesign Quickbooks in-product help system to replace the help content UI with a web browser control embedded in a single help window. 5. Recreated a consistent user experience after the help system redesign by refactoring the help system code to handle the contextual data differently. 6. Fetch help content from multiple data sources in parallel and synchronize the fetching threads to commingle the search result. 7. Maintain several back end services (File doctor tool, automatic task manager, password reset tool) to keep them up and running correctly.
