1) Transaction Processing over XML (TPoX) benchmark
Key designer and developer of the first version of the benchmark:
Chose a real-life scenario from the financial industry and wrote XML Schemas, XML
indexes and the workload statements including XQueries, SQL/XML queries and XML
Developed a high-performance and highly parallel workload driver (Java, JDBC).
Found important issues in the new DB2 code via the use of TPoX, analyzed them and
worked closely with the DB2 developers from different parts of IBM to get them fixed.
Used the benchmark for performance evaluations of pureXML in DB2 on the databases
of the size up to 100 GB. Performed various tuning and achieved excellent results,
which were published and well-recognized world-wide.
2) Integration of the Altova tools with DB2 9 pureXML
Key contributor from IBM to the integration of the Altova’s world-famous graphical tools
(XMLSpy, DatabaseSpy, MapForce, StyleVision) with DB2 pureXML:
Identified the most important DB2 functionality to be supported by the Altova tools and
provided Altova with some optimal implementation details.
Participated in the design and thorough testing of the new features and interfaces.
Took an active role in marketing of the new functionality.
3) Other XML work
Designed and developed new XML workloads to be able to find functional and
performance problems on the early stages of the DB2 9 – 9.7 development.
Used UNIX shell scripting and Perl to set up and automate the workload runs.
Used various profiling tools (tprof, db2trc, db2 snapshot monitor, db2expln / db2exfmt,
etc.) to do the detailed performance analysis and to find the performance bottlenecks.
Found some serious issues (up to 20x performance degradations as compared to the
earlier DB2 builds using different DB2 code), which resulted in the redesign of some
new components and improved the quality of DB2 significantly.
4) Other work and achievements
Converted the DB2 workload containing several complex stored procedures, functions
and triggers to PL/SQL to test the new cross-compiler functionality in DB2.
Worked with DB2 DPF (Database Partitioning Feature), performed database migration,
various tuning / optimizations and other DBA tasks.
Continuously led and developed teams.
Built strong relationships with the DB2 partners including Intel (USA), DaimlerChrysler
(Germany), Altova (Austria and USA), University of Calgary and 1C (Russia).
Prepared and gave various presentations, including for large audiences (XML Customer
Day, DB2 9 Beta Education Day; conferences: CASCON 2007, XML 2007).
Published several papers, some of which are listed in the Selected Publications section.
Siemens AG, Munich, Germany 01.2002 – 10.2003
Software Developer, Researcher

Selected responsibilities and achievements:
1) Java and XML development
Designed and implemented a Java program that customizes an animation for any
Siemens cell phone (color scheme, screen size and other parameters) by applying point,

area, geometric, statistical and color quantization operations from the JAI (Java
Advanced Imaging) libraries to the animation frames.
Developed visual XML and SMIL editors containing various active components using
Java Swing and J2D (graphical tools).
Used the Xerces XML parser (SAX and DOM) to devise algorithms converting XML into
ASCII format conforming to the specified grammar.
Wrote the XSL transformations and XML schemas.
Used Cocoon under Tomcat and MySQL JDBC to support web services using XML.
2) KODI research project
Exploited business models, accounting, billing and charging methods for context-aware
services for mobile devices over 3G networks and proposed extensions.
Developed use cases for various types of context-aware applications and addressed
issues of payment, interoperability of services and roaming using UML-style dependency
and flow charts.
Conducted presentations, led meetings and coordinated work between the three project
partners: Siemens AG, Apollis Interactive AG, Ludwig Maximilian University (LMU).
Wrote the project's annual deliverable.
