  • Strong expertise in Windows Forms.
  • Proven experience building custom UI controls from scratch (inheriting from base controls and implementing custom rendering – not configuring DevExpress/Telerik/Infragistics).
  • Experience working with continuous real-time data streams, where data is pushed to the UI (not periodic refresh).
  • Strong understanding of multi-threaded UI applications (updating UI safely from worker threads, avoiding freezes and stalls).
  • Practical experience in UI performance optimization (reducing redraw cost, minimizing GC pressure, batching updates, preventing flicker).
  • Experience working with TCP / socket-based communication.
  • Ability to clearly explain previous UI design decisions, trade-offs, and the impact on end users.
  • Fluency in English (minimum B2+).
