Description:

The client is looking for a Programmer - Advanced

The client is seeking a highly skilled Application Developer to support the transformation of its legacy Case Management System (CMS), currently built on CA Plex, into a modern, scalable, and maintainable .NET (C#) architecture.

Application Developer II

This role will support the progressive migration of business logic, data access layers, and system interfaces from a model-driven 4GL environment into standards-based, service-oriented architecture, including the development of RESTful APIs to support internal and external integrations (e.g., SLED, DMV, eCitation, Public Index, and partner agencies). The ideal candidate combines deep legacy system understanding, modern software engineering
expertise, and enterprise integration experience within a high-availability, data-sensitive environment.

5. Azure DevOps & Development Standards

Transition development workflows into:
o Visual Studio / Git-based source control
o CI/CD pipelines (Azure DevOps or similar)

Establish coding standards, documentation practices, and testing strategies

Support automated testing (unit, integration)
6. Incremental Migration Strategy

Support a phased modernization approach, including:
o Strangler Fig pattern (wrapping legacy functionality with APIs)
o Parallel run strategies
o Risk mitigation for court operations
