Andrus is a passionate open source developer and an ex-VP of the Apache Software Foundation. He started programming in Java back in 1998, founding a number of open source projects since then. It all started with "Apache Cayenne", a thoroughly unconventional ORM. More recently he created "LinkRest", a framework for model-driven REST data services, and "Bootique", a minimally-opinionated technology for building runnable Java applications. In his day job Andrus is an IT entrepreneur, running a great software company called "ObjectStyle".
