I am the most active developer on LedgerSMB, which accounts for most of my consulting and freelance work. I also offer PostgreSQL-related consulting services and more.

I also am a co-founder of Efficito which offers LedgerSMB ERP hosting for small to midsized businesses. Efficito: Robust, flexible, and open.

Finally I am a principal consultant for 2ndQuadrant and offer PostgreSQL consulting services throughout South-East Asia.
