Required Skills & Experience:

  • 5+ years of experience in ASP.NET (C#) web development.
  • Strong front-end skills with HTML5, CSS3, JavaScript, and any modern framework (React, Angular, or Vue.js).
  • Good understanding of network security principles, firewall rules, ports, protocols, and access control.
