  -Economist-Coordinator & software developer

   

  Main duties: Client/server easy-extensible multi-threading financial Decision Support System developed independently - from analysis & coding to the maintaining & documentation, from OOAD and database structure to the business logic and GUI. After an initial data importing from 3^rd party databases, the system generates its reports from the internal database (in Borland Interbase, Paradox, Informix or other formats) and further provide the possibility of exporting to CSV, Excel, HTML, provide static and dynamic graphs and so on. Reports use the concepts of expert systems, data warehouse and financial analysis (as CAMEL is). Was developed also a compact, stable and quick “shell”, which made possible fast (from 3 minutes to 3-4 days) implementing of new various financial reports and processing (using plug-ins concept) in banking supervision area (50+ reports came in common use during 1,5 years). The security rules and plug-ins sources also are maintained in internal database in memo fields of tables and built as a tree. Database structure is developed for easy spreading over the intranet or internet for using as distributed database for a frequently-changing legal environment and subjects applied to. 4 specifications written. Application was used up to 2005 year.

   

   Tools used: Delphi 5 Enterprise, Borland C++, VC++ & MFC & ActiveX & STL, Informix (client), Interbase 4 for Linux (server & client), Interbase 5.6 for Windows (server & client), Paradox (databases), CGI, HTML, SQL, BDE, MS Windows 95/98/NT/2000, Novel 3.x-5.x (client), Linux (server), Paradox 5/7/9 (design environment used too).

  Ø  Post-graduate studies in State University “Babes - Bolyai”, Romania     Oct 1995 – Feb 2001

   

  Thesis theme – “Some optimization problems in Distributed Databases” (Thesis)

  Publications

   

  "Optimizations of Distributed Databases", Cooperatist-Comercial University of Moldova;

  "Problems of optimizations informational resources placement through minimization of kinetic energy of summary type", Academy of Economic Studies of Moldova; „Information fragments topology”, University „Babes-Bolyai”, Romania and so on.

  Main topics:

  ·  Neural networks, redistributing resources, replacement of information resources.

  ·  General topology and graph theory in computer networks, query optimization, semantic caching, logistic.

  ·  Computers’ network modeling and simulation, WEB DB, DDoS.

  ·  An application in area of optimization of distributed databases using orthogonal algorithms.

  Tools used: Delphi 5 Enterprise, VC++.

    In the 1^st half of my thesis was used theory of classification, topology, OOP, discrete mathematics, distributed databases & systems, neural networks, graph theory and so on together. As result there was obtained an adequate mathematical representation in scope of Distributed Databases modeling (and not only). Applying this model, there was obtained very interesting results in area of automatically replacement of informational resources over the computer net (efficiency increasing from 5 to 250 and more times showed by my application clustexe.zip), semantic caching and distributed security. Developed some ways concerning how to do this. Moreover, using these ways we can repeat these procedures from time to time. In fact, the database fragments will move its position dynamically and automatically after their users. The results were unexpected and can be used for more efficient spreading of database fragments in intranets and even over the Internet. The modern DBMS has already had almost all necessary infrastructure (queries monitoring and some optimization procedures by the request).

   One of possible applications: Suppose, we have to manage the company's database using a few copies of DBMS installed on different computers. We must decide which fragments of our database must be placed on which server. And we must do this efficient. For instance, the information required for hiring department must be placed on the server which is located as close as possible to the users, which are working in this department (this is just a short explanation). If hiring department or other users will change their location, the software, developed according to thesis will replace automatically some information pieces to their new optimal place (server).

    Using these procedures in Internet we can obtain smart self-moved information with a self-tuned optimization. Other valued results concern such areas as semantic caching and distributed security.
