A multi-technology project, for which the components were developed in Java and .NET Core as well as Oracle DB Jobs and Triggers.

The application was developed for the airline I was working for to collaborate with another airline to share the same physical flight to operate to specific destinations. The check-in system for both airlines had to be fed with the booking data from both of the airline's reservation systems.

I was part of designing and implementing the .NET components, which involved a data adaptor listening for changes in the reservation system for the configured flights and a data synchronizer, which would push the flight data to a Kafka topic that will be taken by another Java service and converted to XML and pushed as an XML Datafeed to the check-in system.

The technologies I used in this project are a Windows background service, REST APIs developed in .NET Core and Confluent Kafka libraries, and AVRO schemas.

The project involved multiple microservices communicating with each other through Kafka topics and events.

I developed a WPF application to be used in the kiosks of a luxury cruise. It allows the user to scan the cruise credit card to check the balance, recharge, and print the statement. The application had integrations with external devices like credit card readers, handheld scanners, and PECTAB printers. I used WPF forms with the MVVM model for the development, with SQL express as the database.

My current organization has a message parser that accepts messages from partner airlines using IBM MQ, processes them, and constructs reply messages to be sent out using IBM MQ. The component was a monolith and a legacy application with so many performance issues. I introduced microservice architecture into the system and divided the application into multiple services, introducing Apache Kafka and messaging. The project was implemented successfully and well appreciated.
