I am software engineer and developer currently focused on a Identity and Access Management solutions. I understand and work with technologies such as: SAML, XACML, OAuth, OpenID etc. and techniques: PKI, Federated Identity, Single Sign On, etc. This knowledge allows me to build software that requires secure and reliable authentication and authorization mechanisms. I have experience working on projects for companies like IBM or JBoss. Much of my time I spend on open source projects, among the others: - Apache Amber - OAuth 2.0 framework for building OAuth 2.0 clients, authorization and resource servers in Java (one of the main contributors): - OAuth 1.0a extension to the Java web services framework Apache CXF - Infinispan based Lucene directory for storing Lucene indexes (Hibernate Search full-text search framework) Apart from industry I have wide experience working in academia on various security research projects. I am co-author of the User Managed Specification that extends OAuth 2.0 and has been submitted to the IETF.
