Omry Volk
Data Visualization Developer in Cambridge, United Kingdom
Member since October 14, 2016
Omry is a data science developer who's been writing scientific and geospatial codes and algorithms for the last few years. He's also built complete software from scratch. His main coding language is Python. The work that he's done for projects varies from optimizing a drone's flight path from a polygon mesh, making a gene-spread simulator over generations (using maps and hearth data) to building both the front- and back-end of websites.
