Assess each legacy Delphi application's business logic, data dependencies, and integrations to design an appropriate cloud-native replacement architecture.

Develop migration plans that sequence and prioritize which Delphi applications to modernize first, balancing business risk, technical complexity, and ongoing support burden.

Write clean, maintainable C# code and apply Azure security and identity best practices (Managed Identity, Key Vault-based secrets management) in all newly built services.

Validate data integrity and business logic parity between legacy Delphi applications and their modernized Azure replacements.

Partner with Architecture, Data Engineering, and Security teams to align modernization work with target-state cloud architecture and HIPAA/HITRUST-aligned controls.
