  • Gradually transition from debugging and maintenance tasks to developing new features.
  • Lead the upgrade of ExtJS to its latest version and migration from .NET 4.6 to .NET 4.8.
  • Take ownership of the applications, ensuring autonomy with minimal mentoring over time.

Requirements

Must Have:
