• Lead the migration of the Volunteer Impact backend from VB.NET/.NET Framework to C#/.NET 10, defining the migration approach and executing it incrementally against a live production system • Modernize a custom security framework (70+ custom attributes) into something that works on the new stack, with zero authorization bypasses • Strengthen the existing CI/CD pipeline and, with our quality engineering function, wire in the gates that catch functional and performance regressions before they reach production • Ship migrated areas to production independently and incrementally while the legacy application keeps running • Become the second engineer who can independently cut, validate, and deploy a production release • Identify, evaluate, and replace legacy dependencies that don’t have a path forward to modern .NET, without introducing functional or performance regressions • Make the technical sequencing calls: which areas migrate first, which dependencies get replaced when, and where automated conversion is viable vs. manual rewrite • Lay the foundation for the team to grow by modernizing the stack to one that any C# developer can contribute to
