Employment history
COMPANY Honeywell Ltd., Australia
TITLE Specialist Software Engineer
FROM Feb 2007 – Now
JOB DESCRIPTION
I work on the product called “Digital Video Manager” ([login to view URL]). It performs delivery of video from IP cameras, recording, analysis, alarming. The technologies used are COM, SQL Server, C++, .NET, VB, ASP, Web services, TCP/IP.
My responsibilities include:
- DVM maintenance, bug fixing and submission
- Design and implementation of new features
I developed an adapter for a third-party video analytics product, which takes video and produces an XML stream of events. My relevant achievement was almost bug-free fast implementation which performed stream parsing, XML analysis and conversion. The result was mostly due to the rigorous unit testing and specification adherence.
Currently, I am the leader of the process improvement group concentrated on improving the quality of DVM through varied testing and testing automation.

TITLE Software Engineer
FROM Jan 2006 – Feb 2007
JOB DESCRIPTION
I worked on many projects at Information Delivery group in Information
Engineering laboratory ([login to view URL]),
such as Myriad/SciFly, MIE, EDKMS, SilkenOrb crawler.
Myriad is a framework for generation of coherent reports based on the data from different data sources. Essentially, it is sophisticated manipulation of tree structures, traversal and annotation. The system is using the technologies such as XML, Web services, Onthology(KL-ONE), Servlets, XSLT, RMI and is written in Java ([login to view URL], [login to view URL]). Scifly is an application of Myriad for brochure generation (for example, for marketing purposes).
My responsibilities were implementation of new features, such as
web-services, processing modules, maintenance of existing code,
integration with other products which are based on Myriad.
My relevant achievement was a complete rewrite of the parsing and interpretation module. It was for a high-level language which was a mixture of XML and Lisp, and implementation was very slow as it was based on iterative evaluation of strings (bottom-up evaluation by replacement). I re-implemented it using attributed parser tree approach, which reduced the execution time of Scifly in some cases from 20 seconds to just 1.
MIE is a question-answering system for mobile phones based on the data
from Wikipedia ([login to view URL]). My role was overall system
architecture, integration of different parts of the system,
implementation of disambiguation of terms (by using the data from the Wikipedia disambiguation pages), sentence separation (developed by me, using statistics and POS analysis), mobile client (J2ME, XML). The technologies used were XML, lightweight HTTPD, MIDP 2.0, NLP.
EDKMS is a joint project with Boeing for solving a problem of
information overload in their particular environment. It is based on
Myriad, and uses the ideas of Myriad and SciFly for integration of the
data from different data-sources and optimal presentation of the
information that allows more efficient decision making.
One of the relevant achievements was a performance improvement of the open-source algorithm for XML diffing ([login to view URL]), which reduced the execution time in some cases from 26 seconds to 800ms. The problem was in excessive allocation of small objects. I studied the original algorithm (research paper), identified the steps in the algorithm where the objects can be reused and modified the implementation.
SilkenOrb crawler is part of the PanopticSearch (AKA Funnelback,
[login to view URL]) search engine. It is a tool that allows retrieving of the web-content from the internet, from a group of web-sites. My task was to improve the crawler performance (memory usage, throughput) and achieve the limit of more than 25M downloaded
pages (vs. 10M currently available). The technologies used were Java
(NIO, Concurrency, Sockets).
By using the special data structures: contention-free collections, specialised cache for URLs, reduced disk access, NIO with buffer swapping, reduced string operations, - I was able to achieve the necessary performance improvement.
Finally, as part of my adaptation to the Information Retrieval world, I studied many publications in the areas of:
• General Information retrieval (e.g. “The Turn”, ranking algorithms such as BM25, PageRank)
• Publications from SIGIR workshops
o In particular, Context in IR (mostly SIGIR IRIX)
• CHI
• NLP (discourse analysis, term extraction, POS, generation, parse and dependency trees)

JOB DESCRIPTION
JDK maintenance - AWT API maintenance and development. My responsibilities included fixing bugs and implementing new features in
AWT (java.awt package in J2SE), responding to the customer's emails and helping solve their problems, filing bugs and RFEs in JDK; interaction with Swing and 2D teams to solve cross-team problems and satisfy their needs in AWT API.
From 2004 - AWT Tech Lead. My responsibilities were to control the technical aspects of the work in the group, to design new APIs, control or write specifications, control implementation, resolve cross-team technical problems.
Spec Lead for JSR 260 "Javadoc Tag Technology Update" (until July 2005)
Achievements:
- resolved about 320 bugs(Java shared code, C/C++ support libraries)
- implemented 9 API features(Java API, C/C++ support libraries)
- implemented one internal protocol feature(Java, XEmbed)
- participated in a full rewrite of AWT peers on Unix platforms using Xlib API ("XAWT") where I designed and implemented the foundation for other classes (basis abstract classes and infrastructure), and was monitoring the concurrency correctness of the implementation.
- Presentation at JavaOne 2004 (AWT BOF), JavaOne 2005 (AWT/Swing
BOF, JSR 260 BOF, "Desktop Java Technology in Project Mustang and
Beyond" technical session)
