My Work

I work currently at Slovak Telekom, a.s. in the application and platform innovation department.

As a Service Platform Development Expert I am concentrating on and extending my previous focal points on Telco service evolution and convergence with web architectures (or why I believe in it). I work on a variety of projects covering a wide scope (communications, content, applications, platforms). Since many years I am moving the area of new service creation and implementation forward by advocating the vision of alternative architectural strategies for operators to better meet actual market needs.

I am also coordinating the activities around WebRTC within Slovak Telekom and am keen on establishing competence in this area far beyond “browser telephony”. This work includes technology/business strategic planning, coordination and active development of complete prototypes as well as relevant infrastructures, and understanding the continuous learning process within a Telco as well as propagating lessons learned to wider audiences. I have a “non-conservative” mindset in that regard and hope to contribute positively towards the change that is currently happening within our industry.

I have been the technical manager for Joyn by Jibe Mobile (RCS 5.1 based communications). The service has been launched in market in June 2014. My work involved coordination of the local technical delivery, testing, and cooperation with the project/marketing.

In the past my work was mainly dealt with the core voice network and related architectures. I have been involved in projects and design work 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 coordinate several students’ projects within my company.
