Research engineer
I worked as an engineer on Cluster CONNEXION project whose main purpose was to
enhance old and research new technologies which are used in nuclear power plants.
Detailed achievements:
• Developed overlay peer-to-peer network called ROSA which is deployed over
Internet
• Connected ROSA with OPC UA - OLE for Process Control Unified Architecture
• Implemented contextual services used in OPC UA and ROSA
• Implemented distributed hash table in ROSA, whose purpose is:
– Storing and discovery of contextual services
– Internal routing between nodes and attempt of routing in case of a net-
work failure
• Implemented web application for monitoring live values of nodes registered in
OPC UA
2012 - 2012 TELECOM PARISTECH Paris, France
Intern
As a part of Erasmus internship program, I worked at Telecom Paristech as an intern
while writing a master thesis. The job was to build a smart house model and con-
nect it with an external autonomic management application. During this project I
learned how to work with several technologies and platforms I have not used be-
fore.(youtube://Smart house)
