• 2. Spring Boot stories
• 3. Playwright automation stories

• Analyze security findings and remediate vulnerabilities in Java and Spring Boot application code, third-party libraries, frameworks, Apache Tomcat, and cloud components.
• Upgrade vulnerable dependencies and platform components; apply secure coding practices; complete impact analysis, code review, documentation, and remediation evidence.
• Execute unit and integration testing and partner with testers on functional, regression, and security validation to protect application stability.
• After security work, develop and deliver Spring Boot stories, including REST APIs, microservices, backend services, database integrations, defect fixes, and technical enhancements.
• Develop and maintain Playwright automation stories to improve regression coverage, repeatability, and testing efficiency; support Selenium tests where applicable.
• Design, develop, test, deploy, and support enterprise applications using Java, Spring Boot, SQL Server, IBM MQ, Apache Tomcat, and AWS.
• Build and support event-driven and message-based integrations using IBM MQ, Amazon SQS, and Amazon SNS.
