Let me help you develop an awesome app using Next.js. You'll be amazed at how quickly, together, we can go from idea to polished app. Excelling in Software Engineering today starts with one's ability to evaluate and choose which open-source products and resources to integrate into your solution without drowning in the ever-changing ocean of choices. Making the right choice from the many options available will determine how well a solution stands the test of time. When asked to create a mobile web app to replace an iPhone and Android app I chose to create a Progressive Web App using React and React-Bootstrap with a GraphQL data access layer. On the server, I created a java based GraphQL service replacing web services. Web application, including GraphQL service and access to PWA, is deployed on Tomcat. When I was asked to develop an enterprise authentication solution for our product suite, I chose to base our IAM product on WSO2 Identity Server and implement OpenID Connect in our products using the Nimbus OAuth 2.0 SDK. For a reporting solution, I chose to base our product on JasperReports Server. And, for a solution to consume and transform HL7 messages, I chose Mirth Connect. I enjoy solving complex technical problems through research, analysis, and design, working independently and as part of a team. I strive to create solutions that are scalable, maintainable, and performant.
