Position: Software Engineer. Brief description: Conceptually, this composite software system is fuzzy search service. Utilization of such architecture paradigms as SOA (Service Oriented Architecture) and SEDA (Staged Event Driven Architecture) allowed for creation of an embedded system capable of flexible scaling in order to satisfy given requirements, such as throughput, latency and relevance. Cross-platform aspects of the application were realized by means of 3rd party libraries, such as Boost and Poco. My part in the project was design and implementation of database layer: utilized DBMS was Berkeley DB. In addition, I have designed and implemented inter-module communication, developed system unit-test, took part in integration of 3rd party products (Boost, Poco, Xerces, Berkeley DB). Development language: C++ Project: Cedar February 2006 May 2007, Use The Link, Minsk, Belarus Company: Use The Link. Position: Software Engineer. Brief description: This project involved development of integrated solutions for mobile devices. Main focus was on the market of feature-phones, targeting not only flexible porting to various device platforms but also relative ease of integration into other systems. My contribution to the project was design and implementation of MMS service and interface level subsystems. Roughly speaking, MMS service level is a set of classes providing a neat and flexible interface for loading and saving messages in the storage, and also for composing and parsing massage content with the support of such functionality as DRM. This also included controls to carry out rendering media content. Languages used: C++ Career goals: - The possibility of using new technologies to improve the professional skills. - Increased wages. - Ability to work a lot and see the result. - The ability to use modern concepts of software development. 3
