Requirements description

The Essentials We're Seeking

  • 8+ years of professional experience in C#/.NET with strong focus on Windows Forms.
  • Proven ability to build custom UI controls from scratch (inheriting base controls and implementing custom rendering, not configuring DevExpress/Telerik).
  • Hands-on experience with continuous real-time data streaming to the UI ( data pushed, not polled or periodically refreshed).
  • Deep understanding of multi-threaded UI architecture (safe UI updates from worker threads, no freezes or stalled redraw).
  • Demonstrated skill in UI performance tuning (batching updates, reducing paint cost, minimizing flicker, lowering GC pressure).
  • Experience working with TCP / socket communication and interacting with C++ backend systems.
  • Ability to explain design decisions clearly and articulate the impact on end-user experience.
  • Strong communication skills and experience mentoring or leading developers.
  • Fluency in English (minimum C1) to collaborate effectively with stakeholders.
