• Proactively identify and resolve issues related to code quality, performance, and technical debt to ensure a robust and efficient system.

• Support ongoing system maintenance and enhancements post-migration to continuously improve the system’s functionality and performance.

• Solid understanding of software engineering best practices: design patterns, version control, testing, and documentation

• Experience working with relational databases (e.g., SQL Server)

• Strong analytical and debugging skills
