Summary

I am a qualified Network and Systems Engineer and Research Scientist with management experience in the information and telecommunication industry for 7 years. I have an in-depth variety of skills and experience in the fields of data science, machine learning, data centres, virtualisation, and computer networks and systems in both academic and private sectors in Europe, as well as New Zealand. My expertise, robust technical skillset, ability to communicate technical concepts and information to non- technical audiences, as well as team management and coordination capabilities repeatedly yield successful project outcomes. I have a diverse knowledge-base and high level of personal motivation with the ability to work autonomously or in a team environment, which provides exceptional value to any organisation.

 

Experience

Budapest University of Technology and Economics

Lecturer, April 2019 – Present, Budapest, Hungary

Victoria University of Wellington

Postdoctoral Research Fellow, September 2016 – March 2019 (2 years 7 months), Wellington, New Zealand

I have been working on the enhancement of network traffic classification, measurement data reduction and visualisation techniques in traditional and software-defined networks. Focusing primarily on:

− Application awareness (multi-class classification) using supervised learning (Artificial Neural Network/Back-propagation, k-NN, Decision Trees)
− Anomaly detection (binary classification) using unsupervised learning (outlier detection, clustering)− Heavy-hitter identification using cluster analysis (K-Means, Silhouette analysis) and pattern recognition

− Flow record (big data) compression method using dimensionality reduction (auto-encoders) and generative modelling (variational and generative auto-encoders)

− Flow measurement data visualisation based on Angular Histograms, attribute curves, and D3.jsI also prepared and delivered lectures for courses in Systems Programming (NWEN241), Advanced Network Applications (NWEN304), and Computer Network Design (NWEN302).

Additionally, I set and marked examinations and supervised and mentored both undergraduate and graduate-research students.
