· Troubleshoot and resolve any issues that arise during the migration process.

· Document the migration process, configurations, and any changes made to the applications.

· Robust problem-solving and analytical skills.

· Excellent communication and collaboration skills.

· Ability to work independently and as part of a team.

· Expert to use AI development tools ( copilot, Cline, Cursor, etc.) for reverse engineering.

Application Migration & Refactoring

· Analyze existing applications to understand architecture, dependencies, and migration requirements.

· Refactor or rewrite code in (Java, Node.js, Angular) to align with cloud-native patterns.





· Update application configuration files and connection strings to integrate with the new cloud-based database (e.g., updating JDBC URLs, connection parameters).

· Ensure secure and reliable connectivity using IAM roles, TLS, VPC configurations, etc.

· Collaborate with DB and infrastructure teams to validate integration and performance.

Testing & Validation

· Conduct unit, integration, and performance testing in the cloud environment.

· Diagnose and resolve issues related to connectivity, latency, or timeouts.

· Document migration steps, architectural changes, and configurations.

· Align efforts with DevOps, security, and infrastructure best practices.

Required Skills

· 5+ years in application development and/or modernization projects.

· Strong experience in at least one of the following tech stacks:

Legacy: Java (JDK 5+, Struts, Spring), .NET

· Familiarity with cloud platforms: AWS, Azure, or GCP

· Deep understanding of database connectivity (JDBC, ODBC, ORM frameworks like Hibernate)

· Working knowledge of DevOps practices (CI/CD pipelines like Jenkins/GitHub Actions)

· Understanding of cloud security : IAM, VPCs, encryption protocols

Nice-to-Have

· Cloud certifications (e.g., AWS Certified Developer, Azure Associate)

· Experience with Infrastructure as Code (Terraform, CloudFormation)

· Past experience modernizing mainframe or legacy systems to the cloud
