Ben Summers
Machine Learning Developer in Uppsala, Sweden
Member since April 26, 2019
With a PhD in pure maths, Ben would describe himself as an academic at heart, which means he’s deeply passionate about his work. Since finishing his PhD in 2012, he’s worked professionally as a back-end and data engineer for both a large global company and a small startup. For the past four years, he's been obsessed with machine learning, especially neural networks, and enjoys applying these techniques to solve real-world problems.
Ben is now available for hire

The most amazing...
...project I've worked on is my PhD thesis because it was the first time I was really challenged. Writing did not come naturally at all. I always want to explore.
Employment
Experience
- Web-based Server Monitor and Admin Tools for Medal of Honor (Other amazing things)
This was written in PHP and has lots of socket programming, sessions, and user authentication. The client tool was built using C# and .NET.
