Challenge
Reduce technical debt without disrupting business processes or data quality.
Backend
Enterprise application modernization
Legacy system evolution into modern .NET and Blazor services while preserving operational continuity.
2025 - PresenteRole: .NET developer focused on modernization, backend work, data, and progressive integration with existing systems.
Solution
Incremental refactoring with ASP.NET Core APIs, Entity Framework, and Oracle/PostgreSQL integration strategy, using AI agents to analyze impact, propose refactors, generate regression tests, and review alternatives before changing critical services.
Technical decisions
- Incremental evolution to reduce technical debt without stopping operations or business processes.
- Data layer with Entity Framework and coexistence strategy with Oracle/PostgreSQL.
- Prioritized continuity, maintainability, and predictable deployments over high-risk rewrites.
Impact
Improved maintainability, more predictable deployments, and lower friction for future changes.
Results
- More maintainable code prepared for frequent evolution.
- Lower friction to deliver new functionality on top of existing applications.
- Better encapsulation of data access and lower coupling with legacy systems.
