Worked with ESB from WSO2 where I’ve developed Rest APIs.Created 2 POCs with micro services architecture using Spring Boot, Java 8, Hibernate, Spring Zuul, and Spring Eureka.Implemented in our middleware Java application a new integration with VISA, new APIs in order for a client to be able to change the status of a card. For example one API which expose a feature to block a card in a specific country or to be able to block payments from E-commerce. The implementation was made in a TDD approach.Implemented SAGA pattern in microservice architecture.Worked with Fabric8 form OpenShift where I’ve deployed those microservices.Worked on a messaging project with Apache Kafka and Zookeeper. Using this technology I was able to create topics to handle messages in a better way (having subscribe/publish concept). I have used Apache Spark deployed on Openshift cluster to have some logic implemented for the messages from Kafka. With this application also I have applied some rules (jars) from Drools but within an API exposed by a microservice which is loading the rules and is applying them. Worked with Drools Workbench deployed in Tomcat 8 on Fabric.I have created a consumer for a POC in Android which is faking the notifications from Firebase. It is pooling for updates from a service and is showing the notifications when the data is there.In charge of leading a team of 4 people in order to create 15 microservices following the architecture of PSD2 (Revised Payment Service Directive). Created RESTful API. Used WSO2 platform to deploy Swagger files for these APIs. Handled security by validating JWT tokens in Spring Boot applications.Working with Spark jobs, Hadoop, written Java Spark jobs. I’m using also Hadoop and had some Big Data integrations.Working with Terraform in Online Banking Project. Moving ONB to Cloud, using Infrastructure as code (Terraform) to create infrastructure in the Cloud.Integrate real time flow application with Kafka.
