Software Development: Design, develop, and implement complex Java-based solutions for integration services, ensuring high-quality code and efficient development practices.
End-to-End Application Development: Involved in all phases of development, including system architecture, application design, development, deployment, and automation.
Integration Solutions: Apply knowledge of SOA and Microservices architectures to design and integrate services across various systems and platforms, including RESTful APIs, SOAP, JSON, and MQ.
Containerized Deployment: Develop and deploy Java applications within containerized environments (e.g., Docker, Kubernetes), and ensure smooth continuous integration and delivery (CI/CD) processes.
Performance Optimization: Troubleshoot, debug, and optimize the performance of high-volume, enterprise-level applications, particularly in a banking or financial context.
Agile Methodology: Participate in Agile ceremonies, contribute to sprint planning, and collaborate with team members to deliver quality software on time.
API Development: Develop, test, and document APIs; define swagger specifications, and collaborate with front-end developers and other API consumers.
Collaboration & Problem Solving: Work closely with other developers, solution engineers, and stakeholders to design and implement innovative solutions, taking ownership of assigned tasks and delivering results efficiently.
