I worked with several multinational companies for over eight years on various technical/functional domains and just started freelancing only recently. I had the experience of designing & developing complex software systems right from the scratch and maintaining those in production deployments.
I consider myself a Java Security Expert for I extensively worked with PKI, RBAC, JAAS, JACC, SSO, SAML, OAUTH, etc for many years. I have vast experience in making software for automated upgrades, either for release to release or between iterations in an agile model of deployment. I am an expert at debugging & performance analysis too.
I am quite verse with utilizing and often customizing open source software; the most notable of which i trifled with are OpenSSO (for RDMS based identities & entitlements), CSync2 ( few bug fixes & enhancements), Apache Lucene (integration with Apache Cassandra via a new Codec)
I had the experience in building and maintaining JBOSS clusters with versions 4, 5, & 6; I assure you of timely delivery with uncompromising quality in whatever i do.
Sincerely yours,
Samba Kolusu
