Experience
Client, Account, and Portfolio APIs for myDashboard Application
This dashboard was built with an Angular-based front end with Node.js and Spring Boot-based back-end RESTful APIs. Data provided from the APIs are consumed from multiple Kafka topics. Data is consolidated and saved in MongoDB. MongoDB change stream is used to publish application data change into Kafka topics.
During the project development, I was the tech lead spending 80% of my time as the full-stack developer and 20% reviewing code and architect design. All APIs are containerized and deployed on either enterprise PCF or Openshift. On the infrastructure side, I was also responsible for setting up and maintaining the MongoDB and Elasticsearch cluster on the Enterprise Red Hat Linux with my team.

Digital Claim Document Intake Application
https://www.wsib.ca/en/uploadThis is an Angular-based web app that gives the user the ability to upload claims-related documents. The Spring Boot back end processes the file and triggers an IBM Message Broker message flow to send the document to Kofax for OCR. The collected metadata and file is sent to the TCM content management system via a SOAP service. At the same time, an MDB will process the message and forward it to the Guidewire Claim center and mainframe.
I was responsible for the following:
1. Angular file upload page.
2. Spring Boot microservice to accept file upload and trigger message flow by REST call.
3. Message Broker message flow to process the request and send files and metadata to MQ for Kofax processing.
4. MDB to listen message and updating of the mainframe using CTG.
