Magnus Hagander is a member of the PostgreSQL Core Team and a developer and code committer in the PostgreSQL Global Development Group. He currently serves as President of the board for PostgreSQL Europe.
Magnus is one of the original developers of the Windows port of PostgreSQL, and currently a part of the team that maintains it. These days, he mostly works on other parts of the PostgreSQL backend, recently with a focus on security features such as authentication and encryption.
He is also one of the core members of the postgresql.org infrastructure team, maintaining the servers that power the project, and one of the maintainers of the postgresql.org website. He also contributes to pgAdmin and other related projects.
He's been a PostgreSQL user since version 6 (with some non-serious use of Postgres 95 before that), and currently serves on the Core Team and as President of the Board for PostgreSQL Europe.
To pay the bills, he is a PostgreSQL and open source software consultant at Redpill Linpro in Stockholm, Sweden, where he works on consulting, support and training services, as well as custom development work.
