Role at Effy Tech

From product direction to production delivery

Salek leads requirement analysis, architecture, backend design, product decisions, and final delivery across Effy Tech projects. He focuses on systems that remain practical after launch—not only interfaces that look complete on day one.

Core responsibilities

  • Translate client goals and operational problems into a clear product scope.
  • Define application architecture, backend workflows, data integrity, and integration strategy.
  • Lead implementation, technical review, release planning, and long-term product direction.
  • Keep product decisions aligned with usability, maintainability, and real business outcomes.
