Miklós Prisznyák is a senior software engineer with a scientific background. He graduated as a physicist and worked on his MSc thesis on Monte Carlo simulations of non-Abelian lattice quantum field theories in 1992. Having worked for 3 years at the Central Research Institute for Physics in Hungary, he joined MultiRáció Kft. in Budapest, a company founded by other physicists, which specialized in mathematical data analysis and the forecasting of economic data. It was here that he discovered the Python programming language in 2000. He set up his own consulting company in 2002 and worked on various projects for insurance, pharmacy, and e-commerce companies, using Python whenever he could. He also worked for a European Union research institute in Italy, testing, debugging, and developing a distributed, Python-based Zope/Plone web application. He moved to Great Britain in 2007, and at first, he worked for a Scottish start-up using Twisted Python. He then worked in the aerospace industry in England using, among others, the PyQt windowing toolkit, the Enthought application framework, and the NumPy and SciPy libraries. He returned to Hungary in 2012 and rejoined MultiRáció.  Since then, he's mainly worked on a Python extension to OpenOffice/EuroOffice using NumPy and SciPy again, which allows users to solve nonlinear and stochastic optimization problems with the spreadsheet software Calc.  He has also used Django, which is the most popular Python web framework currently.  Miklós likes to travel and read books, and he is interested in the sciences, mathematics, linguistics, history, politics, go (the board game), and a few other topics. Besides this, he enjoys a good cup of coffee. However, he thinks nothing beats spending time with his brilliant, maths-savvy, Minecraft-programming, 13-year-old son, Zsombor, who also learned English on his own.

Pruthuvi Maheshakya Wijewardena holds a bachelor's degree in engineering from University of Moratuwa, Sri Lanka. He has contributed to the scikit-learn machine learning library as a Google Summer of Code participant and has experience working with the Python language, especially the NumPy, SciPy, pandas, and statsmodels libraries. While studying for his undergraduate degree, he was able to publish his thesis on machine learning. Currently, he works as a software engineer at WSO2, as a part of the data analytics team.
