Worked on an Agile development team with up to 10 Developers, using SCRUM, to develop the ‘client-side’ of web applications, translating functional needs into appealing interactive applications for hospital electronic medical record (EMR) solutions.● Developed the Clinician Window web application, using multiple languages and frameworks such as Angular 10+, Typescript, C#, RxJS, and .NET Core Framework.o Focused on front-end development, displaying complex document formats of patient charts including data, images, and recordings from multiple sources. Designed the user interface, including formatting and data retrieval. o Developed logic to make the website responsive to a variety of layouts (e.g., tablets, mobile devices). ● Collaborated with UX researchers to design and implement better user experiences featuring customized themes, typography, and animations● Used Angular 10 to develop “one-off” prototype web applications, integrating feedback from a usability test lab on new UX features. ● Created an administration module to enact ‘point and click’ configuration. ● Developed backend API endpoints using C# and .NET Core Framework.● Created and updated unit tests using Jasmine, Karma, and NUnit to ensure full code coverage of tests. ● Worked with the release process to automate publishing of updated software versions, using Jenkins.

Developed software applications and enhancements for healthcare industry products. ● Worked on a Windows application to replace outdated, complex, manual workflows by allowing user actions to be automated. Enabled users to initiate a recording of user actions that could be scheduled to execute automatically across multiple environments. Created a graphical representation of user actions to enable debugging and fine-tuning of the actions post recording. Used C#, WPF and .NET.● Developed a ‘plug-in' for the existing ROI Unity software to generate .pdf versions of large document/data sets (up to 100 MB) and enabling enhanced annotation formatting. o Challenged to convert multiple document formats (e.g., Word, Excel, .tiff images) into .pdf version. Created a virtual print driver to generate the document, leveraging postscript files that were combined into the final .pdf.

Engineered a Windows application to create role-based user interfaces to initiate workflow.● Developed a full stack application including the front end, role-based user interfaces, data tables, and data retrieval end points. Used C#, WPF, .NET and SQL.● Provided post implementation support, responding to customer feedback to identify root cause of system error then coding solutions and backporting for earlier versions.● Met with security champions to identify security threats (e.g., SQL injection), develop recommendations and code to mitigate threats. Performed unit testing and handed off to QA. ● Initiated backporting fixes to previous code versions to support legacy codebases.

Supported the build process to create Installers and backport code for software updates, enhancements, and fixes. ● Converted the release process from a series of batch files to a windows-based UI using Windows Forms and C# to increase visibility of errors and to simplify the backporting of code to reduce developer errors. ● Assisted a SCRUM team with developing a website to allow physicians to view their in-patient list. Used HTML, ASP.NET and Web Parts.
