  • Full time job developing network solution design, architecture & implementation and much more. My position of Senior Networking Consulting Engineer is focused on supporting customer during various business cycle – in their pre-sale design or in post-sale support, depending on worked project.

    For Service Providers, I support design from MPLS core and feature-rich provider edge network services. Design and work extends to Data Center VXLAN/EVPN fabric or into Enterprise area to interwork with customer existing infrastructure. This mission requires deep understanding from engineering and designing point of view to deliver functional solution.

    Parts of required skill pack are project management skills, network design skills and customer pre-sale skills.

    From design level, I have understanding from high level topology view to consult customer architecture or services, till low level design for particular feature integration. My consulted design might be fully standardized and RFC compatible or vendor specific only. My position requires excellent skills in routing and switching from enterprise, data center till service provider to support multivendor topologies.
    As I cooperate frequently with customer and different Cisco Business Units, it’s my daily job to use proper project management skills to lead all parties to final solution.
