Software development experience. Experience with React development with TypeScript. Experience withC# / ASP.NET development (.NET Framework and/or .NET Core/.NET). Understanding of object‑oriented programming, design patterns, and clean code practices. Proficiency with Git workflows (PRs/MRs, code review, branching strategies).

Preferred Qualifications

Building complex UIs in React with design discipline (component boundaries, composition, maintainability). Establishing pragmatic state management strategies for designer-style workflows (local vs shared state, derived state, async orchestration). Applying patterns for component-driven development: design systems, reusable primitives, accessibility-first composition.

Implementing clear integration patterns when bridging different UI paradigms (e.g., React with Web Components / IDS). Experience with incremental modernization and interoperability with legacy stacks (knowing what to replace vs wrap vs isolate). Experience testing for UI architecture (component tests + integration tests to reduce regressions).
