WG Chair Biographies

William has over 25 years of experience as an executive of core Internet infrastructure, including working for Network Solutions/VeriSign on the InterNIC project. This project involved Internet numbering, domain names, and directory services and resulted in the creation of the Regional Internet Registries (RIR). Currently, William is Senior Vice-President of Addrex, Inc., the pioneer in the market for IPv4 number blocks. He has spent the past ten years collaborating with global communities to help the Internet to keep growing while we work on adopting IPv6.

William has served as the chair of the RIPE Accountability Task Force, helping to document, review, and publish the findings for the RIPE community's accountability post-IANA transition. Now, as the co-chair of the RIPE Database Working Group, William has led the working group forward, removing roadblocks that have existed for many years and undertaking initiatives to clean up the RIPE database.

David Tatlisu is a network engineer from Berlin.

As a digital native, David cannot remember a time without the internet. In his journey from running servers in his parent's basement to play video games with his classmates to running intercontinental networks as his day job, David's life has revolved around the Internet.

Davids fascination with the Internet and RIPE in particular began when he was in sixth grade, when he stumbled upon presentation archives and got hooked. He cannot imagine a world without the community of dedicated individuals that helped shape the Internet to what it became today, and tries to support where he can.

David started working in IT in 2018, got his own ASN in 2020, became a full-time network engineer in 2021, and finally attended his first in-person RIPE meeting in 2022.
