About Me

I’m a software developer and PhD graduate based in Munich, Germany. I am currently working at Cliqz, developing innovative, user-empowering, and privacy-preserving software in the browser. Specifically, this is Cliqz’ and Ghostery’s anti-tracking system, which prevents online tracking of our users.

I am interested in Decentralised and Federated tech, and am a keen self-hoster. I occasionally post things on the posts page.


Software Developer, Cliqz

2015 to present

As part of the privacy team at Cliqz I am primarily responsible for Cliqz anti-tracking technology. Highlights include:

  • Integration of Cliqz anti-tracking into Ghostery 8.
  • Building the data analysis required for the whotracks.me website, and contributing regularly to blogs there about online tracking.
  • Development of the data aggregation pipeline behind anti-tracking which deploys data-driven whitelists daily, using Spark and Luigi as core technologies.
  • Implementing intelligent anti-tracking on mobile using React-Native as a Javascript runtime. This work enabled parts of the Cliqz browser extension to be run in our mobile apps using the same code base.
  • Wrote multiple whitepapers and articles on online tracking and privacy, and spoke at events including PrivacyWeek 2017.
Technical Consultant, University College London

March 2015

Short contract to implement a tool for the analysis of AIS shipping data. The resulting tool was open sourced and is now being used for various tasks on the Shipping in Changing Climates project.

PhD, Imperial College London

2010 to 2015

My thesis, entitled “Multi-agent Based Simulation of Self-Governing Knowledge Commons”, investigates the application of self-organising governance, as observed in social systems my political economists, to socio-technical systems which manage of information and knowledge.
