Experience

2005-present Working at Xlab:
  • design and implementation of a distributed server architecture and an interactive client for 3D visualisation of geographical data, with data being fetched from the Internet in real time as the user navigates through the environment in order to visualise and inspect results of simulations of natural phenomena (e.g. river flooding, etc.) in realistic environmental context.
  • design and prototype implementation of a framework for dependable service composition in large, globally distributed service-oriented systems in FP6 research project DeDiSys; the framework includes a dependable discovery service and a system for dynamic formation of agreements on non-functional (QoS) properties of the composed services.
  • design of an architecture and data model for a web portal for management of certificates of origin of electrical power traded in local power markets,
  • design of algorithms for specific NP-hard network flow optimization problems used to model prices of electrical power in local power markets,
  • design and implementation of an adaptive per-application firewall based on iptables, used in XtreemOS FP6 research project,
  • design and implementation of real-time analysis of ECG signal with DSP algorithms,
  • design and implementation of a system for fully automated remote installation of an in-house Debian-based Linux distribution on dedicated servers used by XLab's ISL product.
  • design and implementation of a computer network monitor Argus, used to monitor in-house servers and cluster nodes.
1998-present

Contributing to the Gnome Project as one of the core developers and maintainer of the GnomeMDI API throughout all the 1.x versions of the Gnome core libraries.

I am the initial and principal developer and the current maintainer of GHex, a binary file editor, and used to maintain GGV, the Gnome PostScript viewer, for years.

I have also actively contributed to ORBit, a free CORBA 2.2 compliant Object Request Broker used by Gnome; Bonobo, the GNOME component framework; and many smaller end-user applications.

2000-2005 Working at Active Tools:
  • projects for Axceleon, Inc:
    • design and implementation of the next generation of EnFuzion clustering software,
    • porting and testing EnFuzion on various new combinations of OS and hardware platform, including Linux on IBM zSeries, Linux and HP-UX on Itanium 2 and Linux on AMD Opteron,
  • projects for IskraTEL, d.o.o.:
    • porting Linux kernel and basic userspace utilities to a custom PowerQuicc III based board; design and development of drivers for the PQ3 network core,
    • design and implementation of a web-based licence management system using MySQL and Apache Tomcat,
    • design and implementation of network backup software for data on embedded telecommunication systems using the Java 2 platform,
    • design and implementation of networking and telecommunications system software running on VxWorks OS,
    • performance analysis of network protocol stacks in Linux and VxWorks operating systems,
    • lecturing IskraTEL developers on embedded and real-time Linux software development,
  • projects for Turbolinux, Inc.:
2002 Designed and implemented a new version of MINT, a UNIX/X11 application for recording and displaying temperature and humidity data from climatic test chambers, featuring better integration with GNOME desktop, enhanced printing and plotting capabilities. This version is used at pharmaceutical company Lek d.d. and has also been validated by the FDA.
1998-2001 Worked part-time at the Jozef Stefan Institute at Department of Digital Communications and Networks, where I have developed a set of tools for visualization and editing of voxel-based 3D models, which were used for displaying and editing a 3D model of human heart, derived from the Visual Human Dataset data. The model was then used for simulation of heat transfer during an open heart surgery.
1999 Reviewed book Writing Gnome Applications (ISBN 0-201-65791-0) by John R. Sheets for Addison Wesley Longman, Inc.
1999 Designed and implemented a UNIX/X11 application for recording and displaying temperature and humidity data from climatic test chambers. The application has been validated by the FDA and is now used at pharmaceutical companies Lek d.d. and Bayer-Pharma.
1998-2000 Designed and maintained a WWW site for the Danube PCU at http://www.rec.org/DanubePCU.
