• Pipeline Re-architecture: Migrate and re-architect legacy Perl batch jobs and crontab pipelines into modern Python-based services. • Workflow Orchestration: Design and implement orchestration using Prefect or Airflow, including alerting, observability dashboards, and safe job re-run capabilities. • Modern Observability: Instrument services with structured logging and metrics (CloudWatch, or Grafana) to eliminate the need for direct production server access. • Data Layer Ownership: Manage the data layer for file ingestion: landing raw scheme files to S3, parsing/transforming them, and persisting to PostgreSQL or RDS for reconciliation. • Financial Domain Logic: Process and reconcile payment scheme files (clearing, settlement, chargebacks) from card schemes and acquirers. • Engineering Standards: Contribute to architecture decisions, write technical documentation, and establish best practices across the team.

• System Implementation: Support the re-architecture of legacy Perl batch jobs into modern, maintainable Python services. • Operational Reliability: Assist in implementing workflow orchestration (Prefect/Airflow) to ensure safe job re-runs and system stability. • Observability: Help instrument our services with logging and alerting (Grafana/CloudWatch) so we can monitor systems without direct production access. • Data Transformation: Work on data ingestion pipelines, moving raw data to S3 and transforming it into relational database records.

• Support a large-scale application modernization initiative focused on migrating enterprise applications from .NET Framework to .NET Core/.NET 8+ • Execute the majority of application conversion, remediation, testing, and documentation activities across the portfolio • Work closely with the Senior .NET Application Modernization Consultant (Pod Lead) • Implement established migration patterns to ensure successful modernization outcomes • Port application code from .NET Framework to .NET Core/.NET 8+ using approved modernization approaches and tooling • Execute application modernization activities using AWS and Microsoft migration tools • Remediate compatible and upgradeable NuGet package dependencies • Convert and modernize T4 templates as directed by technical leadership • Implement modern dependency injection and configuration management patterns • Apply modernization standards, coding practices, and architectural guidance established by the Pod Lead • Execute confidence testing and validate functional parity against defined acceptance criteria • Troubleshoot and resolve migration-related defects and compatibility issues • Document modernization decisions, implementation approaches, and technical findings • Contribute to migration runbooks, knowledge-sharing materials, and project documentation • Collaborate with architects, senior consultants, QA resources, and project leadership to ensure successful delivery

• Lead the .NET Framework to .NET 8+ modernization strategy across the workstream • Establish technical standards, migration patterns, and quality expectations • Make and document key architectural decisions regarding: Distributed transaction modernization (DTC replacement strategies), ASP.NET Web Forms migration approaches, WPF application disposition (retire, retain on Windows, or rewrite) • Perform hands-on modernization of the most complex application components • Lead remediation of incompatible NuGet dependencies and package modernization efforts • Reverse-engineer and replace private packages where source code is unavailable • Review and approve modernization work completed by staff consultants • Ensure functional parity, maintainability, and performance of migrated applications • Evaluate where modernization tooling can accelerate delivery versus where manual intervention is required • Partner with delivery leadership to identify risks, dependencies, and mitigation strategies
