He started out his career as a student worker, over at the Space Applications Services, for one month in august 2005, where he worked on the setup of a SELinux webserver. He then became a PhD Researcher, over at K.U. Leuven in Belgium, where he worked for a total of 5 years and 5 months, between August 2007 and December 2011. It was during this time that Bitcoin started gaining popularity, and when Pieter may have first heard about the platform.

Bitcoin Core Developer

As a Bitcoin developer, Pieter has had over 600 contributions during the last year on GitHub3, most of them revolving around Bitcoin and its underlying platform, the blockchain.

The team working for the company came together because they are strong believers in the potential of Bitcoin and blockchain technology to shape our future and change our financial system. While various controversies have formed around Blockstream employees, the firm is still seen as trustworthy, and capable of making a positive impact.
