    Software engineer (C/C++, obj-c, Python, Matlab, R, ML algorithms)

    Belarus - Last active: 14 hours ago - Tests: 7 - Portfolio: 5

    The last 5 years I have worked mostly as a C and C++ developer in a field of process automation and control (SCADA). Familiar with OOP and TDD, Design Patterns and different methods of software development (waterfall, agile). I have a good experience in the development of multithread client-server applications, windows services, dll-s and cross-platform libraries. One of the specific features of my job was writing readable and easy-portable C-code covered with tests.Another interesting feature is working in small groups dealing with frequently changing goals. The major benefit of this style of work is a great experience on all levels of software development process (from project design and requirement development to final tests). Besides, I have a great interest in the research of new technologies and IT science related fields.

    Ethical Hacker and Digital Forensic Investigator

    Mexico - Last active: 12/03/2014 - Tests: 3

    For the past seven years, I have been learning about the information security world, working as an CEH (Certified Ethical Hacker). With some of my co-workers, i have participated in a lot of projects, strictly focused on Information Security. Also, as we evolve and grow in this area, we have trained ourselves in Forensics Sciences, attending clients who need to know what happened after a contingency. I consider myself a self-taught person that likes to grow and that is not afraid of challenges or difficult cases. At this moment my priority is to teach and so much to share the little knowledge I have gained over the years, as well as learn from those who have traveled a different path and with this keep on growing.

    Software Architect

    Greece - Last active: 04/28/2014 - Tests: 3 - Portfolio: 6

    I finished my degree, BSc Honours in Computer Science at the University of Leeds, England, at the age of 22. Since then I have had more than 15 years of experience in building large scale applications using Delphi, C++ Builder, Microsoft VB, Microsoft C++ and Microsoft C#. Other skills involve 3D programming with DirectX, OpenGL, and HLSL. I have a very good physics and mathematical background which allow me to easily develop physics simulation systems, 3D visualisation systems and deal with problem solving. I can easily program client/server multitier applications that involve network communications such as TCP/IP programming, SOAP and a lot of other proprietary and standard network protocols, such as POP and Web Services among others. All application programming at some point involves storing data in a persistent storage. I have been writing applications that span over from custom database development, such as binary tree/hash tree indexing units, to using ready made relational database systems such as SQL Server, Interbase, Oracle and Access.
