Full dev cycle: design/architecture, development, debugging, testing, deploying, support. 06.11 – 06.12 – developed a documents backup system of MS Exchange user data. Data are read via EWS (Exchange Web Services) and stored in .PST file (with no usage MAPI and any other libs). Tools: c++, STL, WTL, MS Exchange 2010, openSSL, gSOAP, IDA Pro, reverse engineering. 03.10 – 05.11 – database (and workplace) for large electricity transportation company. Accounting of electricity consumption, gathering data, report generation and many other functions to supply workflow in whole. Deployed in several branches around Leningrad area. Tools: c++, STL, WTL, Oracle 11.1g (OCCI, stored procs), COM, MS Excel, svn. 05.08 – 02.10 – automatic test system for MDS in mode 24x7x365 with logging and tracking of any errors and malfunctions. Checking of data integrity and routing . 10.07 – 04.09 – throughput improvement, debugging and new functions implementation for legacy application – Message Delivery System. The messages are any payment documents. The clients are regional payment processing centers of central bank . The throughput was increased from 70K up to 10M messages a day per direction . Tools: c++, STL, WTL, ATL, C#, .NET 3.5, Oracle 9.1, IBM WebSphere MQ 6.0, SMTP, svn.

Full cycle: design, development, debugging, deploying, support. 05.06 – 09.07 – BEST project – Back End System Testing – cross-platform system for automatic testing of e-trading systems. Wide and flexible facilities range for performance testing. Extensibility with plugins. Done: developed real-time subsystem for capturing data transmitted between system modules under testing. Designed and implemented GUI of whole system and its parts. 07.04 – 04.06 – TestHarness project – system for automatic testing of e-exchange (schwab.com). Automatic testing is based on test-scripts on JScript or internal language with powerful framework API.
