Description: This position is responsible for participating in the refactoring of the PROTECT case management system to ensure that it is cloud ready as part of the 2-year modernization effort. This position serves as a member of the core team that includes members of the existing DAIT team and IT contractors. PROTECT is the in-house developed comprehensive case management system used by all 71 District Attorney offices across the State (1600 users). The system is a crucial tool for the operation of the DA offices as well as State justice partners (DOT, DOJ, DOC and CCAP) through various interfaces. The system is currently SQL client-server based (VB.NET). The modernization plan involves moving much of the processing from the client to the back end and middle ware and keeping a thin client application. We are modernizing in place with the new code being rolled out as it is refactored by feature/segment. Example Responsibilities: • Collaborate with the development team to modernize a legacy VB.NET desktop application. • Implement event handlers to manage asynchronous processes and improve application responsiveness. • Create and optimize batch jobs for efficient data processing and system performance. • Integrate event handlers, batch jobs, and message queues with external APIs, services, and third-party systems. • Work on migrating legacy interfaces (data exchanges between justice partners) to modern services using .NET Core and other .NET technologies. • Implement RESTful APIs and integrate third-party APIs as needed. • Design, develop, and maintain scalable and efficient web applications using ASP.NET MVC, Angular, React, or similar front-end frameworks. • Participate in code reviews, debugging, and performance optimization to ensure high-quality and robust software solutions. • Integrate security controls and defensive programming practices into .NET codebase, including input validation, output encoding, secure error handling, and logging. • Implement security headers, content security policies (CSP), and cross-origin resource sharing (CORS) policies to protect against web-based attacks and unauthorized access. • Evaluate and recommend security tools, frameworks, and technologies to enhance the security posture of .NET applications.   Call 502-379-4456 Ext 100 for more details.
