Matchpoint
During 2007 and 2008 I worked on a document analysis tool called “Matchpoint”.
The idea is to parse the document by identifying content blocks and then find certain keywords within the context. The document is tagged based on the found information.
I did the software architecture first, creating the concepts, entities and relations,and identifying crucial parts of the system.
The heart of the system is the parsing engine that identifies segments of document, for example education, experience, and so on. All the permutations of the segments are used, and the one that matches the most segments is selected for further analysis. Each of the recognized segments is then searched for the keywords. Each keyword has appropriate tags assigned, and this way the document is in the end tagged.
Since the algorithm has to analyze documents in different languages, using semantic algorithms seemed a bit too complicated, so I went with regular expressions.
The documents can be emailed or uploaded by FTP to the web server, where is a Windows service monitoring configured folder. A .NET console application is then run to convert document to plain text using IFilters, and then to run the analysis, and upload the data to the Microsoft SQL Server database in the end.
Users can use a web application built on ASP.NET Web Forms to search and view indexed documents.

Car trading B2B
During 2oo8 I worked on the vehicle auctioning platform for a Swiss company.
Frequent discussions with my close associate Saša Klačar, who did the requirements collection and communication with the client, resulted in well documented software architecture.
After defining the system entities and relations, I managed a team of experienced developers went on to implement the system using ASP.NET Web Forms for the front-end, .NET, C# and SubSonic for the middle tier and Microsoft SQL Server as the back-end.
I have also designed the database, scripted SubSonic, implemented a part of DAL, and created a Windows service for XML data imports from an external source.
Following the loose Agile process, we have first released a user interface mock-up, which triggered several system redesigns and resulted in better specification in the following releases.
The better part of the project was done, but it was at a point stopped by the client, even as they were very satisfied with our results, but it was caused by the company’s internal problems.

DBN
DBN is an online publishing platform primarily oriented on the Austrian audience.
Its specific newspaper-like layout turned out to be very successful, as the site has a lot of unique hits. It took a lot of fine tuning to achieve good performance.
The name “Du bist Nachrichten” (You are news) implies that the users influence the content by voting, thus promoting the most interesting articles.
If you are interested to see this in action – have a look here, hope you like it.

Serbian Archives of Medicine
During 2006 and 2007 I was working on the web publishing platform for “Serbian Archives of Medicine” Journal of the Serbian Medical Society.
The requirement was to create a system that would accept the submitted articles, routing them through the complex system of administration, reviews, revisions, edits, and so on until they reach the publication.
On the other hand, there was a need to put the existing printed editions online as well.
I have presented to the revision board my analysis of the entities and processes, shown some ideas how to handle them in the system, they loved it, and I was hired to do the job.
After several iterations of architecture revisions, I have designed the database in Access (hosting limitation) which was later migrated to Microsoft SQL Server.
The web application was implemented in ASP.NET 1.1 WebForms, as it was the platform available for hosting at the time, using C# and NUnit for testing.
The design was aimed for clean overview and quick loading times, implemented in XHTML (as far as ASP.NET 1.1 WebForms allow), CSS, and enhanced a bit with JavaScript.
The document management system was a real challenge, since the client had a complex process, but in close cooperation it was implemented successfully.
The system was later a bit tailored and deployed to [permalink href=”247″]Serbian Dental Journal[/permalink] web site.

Netviz
During a good part of 2006 and 2007, I have created the software architecture and managed a team of experienced developers to create a Healthcare industry related visual networking tool for a Swiss consulting company.
System architecture specification was my first focus, documented in detail and frequently communicated to the client.
The project was done using loose Agile process, following the mantra “Release early, release often”, so system wide changes were continuously propagated and implemented.
The architecture and system entities and relations design were growing and changing during the project, and I am proud to say that we have come up with a great product in the end.
The software was implemented in Java, using JUNG Graph framework and XML as the data source, using JUnit for unit testing.
The highlights
- Complex data queries (could be performed using commands as well as GUI wizards)
- Data filtering
- Advanced visualization mechanics
- Data source was flexible (easily changed from files to web service for example).
