   Kafka & Messaging Systems: I\'ve worked extensively with Kafka, designing and maintaining topics for smooth data exchange in a product named Collection. I handled both subscription and publishing sides, ensuring real-time communication between systems. Modernizing Systems: I migrated legacy mainframe systems to modern Java-based vendor-hosted applications, using Java 8 and JDK 21, to improve scalability and reliability. Cloud & Infrastructure: I deployed and managed applications in AWS and OpenShift environments. Using Terraform, I automated infrastructure deployments, making setups consistent across development, staging, and production. Microservices & APIs: I designed RESTful APIs to connect microservices, built PostgreSQL databases with optimized queries, and used Docker to containerize applications for smooth deployments across environments. Monitoring & Performance: I used Splunk and Dynatrace to monitor and troubleshoot systems, making sure performance stayed top-notch and issues were fixed before they impacted users. CI/CD & Automation: I automated build and deployment pipelines with Jenkins, Gradle, and Terraform, and streamlined artifact management with JFrog Artifactory. I also used SonarQube to check code quality and security. Teamwork in Agile: I actively participated in Agile practices like daily scrums and sprint planning, working closely with teams to deliver projects on time. I also used tools like Digital.ai to improve workflow and collaboration. Security: I identified and fixed security vulnerabilities with tools like Kontra to ensure applications met industry standards.
