• Design, build, and maintain full stack applications (Python backend, web front end) to support batch job monitoring and operations
• Re-architect batch workflows to run on AWS-native services (e.g., AWS Batch, Lambda, Step Functions) as appropriate
• Analyze existing PERL scripts and on-prem batch logic to identify functionality, dependencies, and edge cases prior to refactoring
• Write automated tests to validate that refactored jobs produce equivalent results to the legacy systems
• Collaborate with cloud engineers on infrastructure, deployment pipelines, and cutover sequencing for migrated workloads
• Troubleshoot and resolve data or processing discrepancies surfaced during migration validation
• Document refactored logic, architecture decisions, and operational runbooks
