Developer Backend

As a software development partner for a very large enterprise financial products and services firm listed in NYSE, you were involved in re-architecting and migrating 30-year legacy systems to cloud-based microservices on AWS. These systems are crucial for their trading, journal, and bookkeeping platforms. Your contributions included developing an event-driven ETL pipeline using AWS services to efficiently transfer end-of-day securities data from the mainframe to a relational database. Additionally, you built highly resilient and available containerized microservices to enhance the overall system performance. Automation played a key role in your work, as you automated build and deployment processes using Jenkins and Terraform across various environments such as Sandbox, Dev, QA, UAT, and Prod. This streamlined the development lifecycle and ensured consistency across different stages. To maintain code quality, you wrote unit tests that provided a test coverage of over 80% for the entire application. Moreover, you created a regression test suite to validate the accuracy and correctness of the software after implementing enhancements and modifications. The technologies you utilized in this project include Java, Kafka, Groovy, Jenkins, AWS services like EC2 and ECS, Docker for containerization, and AWS Glue for data integration. Your expertise in these tools and technologies was instrumental in successfully modernizing the legacy systems and ensuring their seamless operation on the cloud platform.,
