Responsibilities:

• Involve in the design, development and testing phases of software development using AGILE methodology with Design Thinking and SCRUM.
• Set Swagger API doc for new endpoints of the service, in groovy YAML file.
• Swagger Java code generator, to create API Client.
• Implement endpoint in the orchestrator (in Node JS or Spring Boot backend, that “orchestrate” rest calls as a proxy to the endpoint in the domain-service )
• Implement endpoint in the domain-service (java REST service), with Spring Boot, for dependency injection binding, also hibernate, and jersey dependencies.
• Implement Configuring repo, to manage Dynamic properties, to be easily updated.
• Unit Test with JUnit and Mockito, Integration test with Wire-mock in Docker.
• Lead team, in all the technical stuff and review their PRs and code, to improve their best practices, and design patterns to be used.

Lead Java Backend Developer

Confidential

Responsibilities:

• The purpose of this project was to prove that we can change currently used S3 AWS service.
• Created a Minio lib that consumes MINIO server create, get, update, and delete, buckets, objects and folders.
• Making that methods and Objects match with the once used in S3 AWS. So that current service using S3 could change implementation to MINIO, decoupling the need to use AWS.
• Did Minio library jar
• Implement Objects and Methods that match to S3 lib
• Made Unit Tests with Mockito and Junit
• Test jar, implementing it services where S3 was being used, with just the need to change of the client object, changed from S3Client to Minio Client.
• Check logs in Splunk querying the service, or inside the same pod.

Environment: MicroServices architecture in Kubernetes and AWS S3, Jenkins CI/CD, Minilo lib, Java 8, Tomcat 9 and spring, Guice, JDBC, JUnit and Mockito.
