I have been working in the medical field for the past 10 years revolving around interoperability, integration, and automation. For the past 6 years, I've been focused on Mirth Interfaces with the following design concepts: - HL7 data coming from EMRs/EHRs - Text and CSV files from SFTP servers and Google Cloud Buckets - Data processed and formatted for PACS, Dictation systems, and receiving EMRs/EHRs - Data processed and formatted for warehousing and analytics My experience defining, designing, and integrating with different EMRs revolves around my time at Shasta Networks and Medford Radiology Group. I built and designed interfaces at Shasta Networks for clients that used Cloverleaf and some that even used McKesson. I worked directly with a McKesson engineer while I was at Shasta Networks to incorporate a stored procedure that allowed us to receive updated patient records based on the stored procedure and a specific update to the database for the patient. As for the interfaces at Medford Radiology Group, the majority of our clients were using Epic and it was my responsibility to ensure ADTs, ORMs, and ORUs, passed to the correct systems such as our Fujifilm Synapse PACS, RIS, and Nuance PowerScribe. During my time at Shasta Networks and Medford Radiology Group, I created design documentation to not only help those who may come after me but to help the project move forward more efficiently and to create a better understanding of the workflow and increase clearer communication between me and the other IT teams. There were times that I had to directly work with the client's IT, networking, and interface teams to see a project through from the first kick-off call all the way to go live. I feel that being able to work directly with the client and the teams gave me the ability to gain the experience of communicating with a diverse group of personalities and an understanding that we are all striving for the same goal. I desire to work with companies and clients that strive to create significant and positive changes while having a culture of diversity, respect, and positivity.

I am a Java Web Developer, working as freelancer, mainly in Upwork. I am very passionate with Java and JVM technologies. My experience mostly in developing Software As A Service (SaaS) platform, business computing and information system area, using Bootstrap, Angular JS or JSF as UI Components or web framework, Spring Core, Spring MVC or JBoss Seam as Restful API endpoint and or Integration framework, and Hibernate as favorite Java Persistence API (JPA) implementation wrapped by Spring Data component. If my clients requires no casual application or web server, I like to use Spring Boot for simpler development and deployment of the application. I am also interested in database design and software design. I believe that great software not only mediocre work of typing, but also comes from thoughtful process. I believe in TDD, and also believe that tests code must be written, organized as good as the source code it self and is integral part of the source code. I am a quick learner, and In my spare-time, I am writing some personal open source project and small proof-of-concept about java-related stuff in my GitHub public repository. My primary machine is linux desktop with 1TB NVMe SSD and 64GB or RAM. I have macbook pro 15 for testing purpose and to allow me mobile occasionally, if needed. Communication is important in remote work, and for this purpose I have 2 link dedicated internet connections to my workspace. If you need my detailed skill abilities, below is what I have experienced in: - Software Design, Database Design, and microservices/Micro-services/micro services architecture. - JPA 1.0, JPA 2.0, with Hibernate. - Bean Validation Specification with Hibernate Validator. - Dependency Injection with Java DI (JSR-330), Java Context and Dependency Injection for Java EE Platform (JSR-299), and Spring Core as most popular (but non-standard) Java Dependency Injection Framework. - Java Web Framework with Spring MVC and JSP, or Java Server Faces (JSF) with Facelet and Primefaces. - Spring Boot, Spring Data stack. - Generated / scaffolding web application using JHipster. - Java Web / Application server with Tomcat, Wildfly, or Websphere AS. - Logging with SLF4J as a wrapper to Log4J or Logback. - JUnit or Test NG as testing framework. - Ant, Maven or Gradle as build and dependency management tool. - HTML 5, CSS 3, JavaScript, JQuery, Twitter Bootstrap, transparency.js, and angular / angular.js - Third Party API such as Xero API, Open ERP Java API, Braintree Payment API, Stripe Payment API, and Social APIs. - Linux, Mac or Windows. - MySQL, PostgreSQL, Oracle, or Microsoft SQL Server for RDBMS. - Couchbase or Mongo DB for No-SQL solution. - Elasticsearch (ELK) stack or pentaho for data integration, advanced search, reporting and data analysis solution.

I help companies build scalable Adobe Experience Manager (AEM) platforms and high performance web applications using Java and React. I’m a certified AEM Developer and Full Stack Engineer with a Bachelor’s degree in Computer Science and over 6 years of hands-on experience building enterprise web platforms across industries such as healthcare, construction, banking, and finance. I’ve worked with agencies including Valtech, Adjacent, and Codeland, where I built and improved AEM platforms, developed custom components, and migrated projects to AEM 6.5 and AEM as a Cloud Service. I also have experience working with AEM Edge Delivery Services, helping teams build faster and more flexible content delivery architectures. My work includes backend development with Java, Sling, OSGi, Servlets, and APIs, as well as frontend development using JavaScript, React, and modern web technologies. I’m comfortable taking ownership of tasks end to end, from designing backend services and APIs to building frontend interfaces and integrating them into AEM or standalone web applications. I regularly work with REST APIs, GraphQL, Dispatcher configuration, performance optimization, and external system integrations to ensure applications are scalable and reliable. I also have experience with automation testing using Playwright, building end to end tests for critical user flows to help teams maintain quality and catch regressions early in the development process. I enjoy writing clean and maintainable code, improving the authoring experience in AEM, and collaborating closely with designers, product teams, and stakeholders. If you're looking for someone who understands AEM from backend architecture to frontend implementation and can also contribute as a full stack developer with Java and React, I’d be happy to help. Feel free to reach out if you need help with AEM projects, Java backend development, React frontend development, API integrations, automation testing, or performance optimization.
