My Work
I work currently at Slovak Telekom, a.s. in the core and control department.
As a senior designer I am responsible for the core voice network and related architectures.
I am working mainly in the area of application architecture and design, VoIP/NGN/IMS platforms, presence/instant messaging (SIP, XMPP, RCS), web service integration, new service creation and implementation, and the general evolution towards a converged service architecture.
Moreover, I am coordinating several students’ projects within my company.
