Stephen Hellberg:
Dr Stephen Hellberg started conducting software engineering research within computational science - developing scientific 'supercomputing' software with distributed and parallel computers. The maturing of these systems facilitated economic development of and building significant enterprise business systems based on huge databases on ever larger server hardware, such as corporate data warehousing, enterprise application integration (EAI) and data mining - earlier generations of Big Data and Analytics! After assisting enterprises construct, use and integrate such systems as a technical infrastructure consultant and solutions architect, he has spent the past 10 years supporting IBM customers on IBM SWG Products with Java, specifically those employing the Hotspot JDKs when leading a L3 support team, on various UNIX enterprise platforms (Solaris, HP-UX, etc.) and with a variety of software stacks (mostly Websphere-based). Presently, my responsibilities concern issues associated with assisting customers and products transitioning within the IBM java ecoysysem, whether thats helping acquisition teams onto IBM java, or across our server platforms, adopt upcoming releases like Java 7, or departing from the end-of-supported lines such as 5.0 (similar support to that provided towards the end of IBM's 1.4.2 java); I participate with our developments leveraging OpenJDK, and I am frequently engaged to assist with performance matters with IBM products when employing the non-IBM HotSpot JVM.
