    Over the last 4 years I have been implementing and supporting various server infrastructure components - Portlet 2.0 Container, Web Server, etc. - and have taken care for the security of those components - that includes compliance checking, designing and implementing security patches. I have solid Java programming experience (more than 7 years) and a very extensive security related knowledge - both in application security and session management security. I am seeking opportunities to use my experience in design and implementation of stable and secure applications and in improvement of the security level of existing code. Prior to that I have 2 years experience as a team lead of Quality Management team so I am familiar with the best software testing strategies and I am capable of managing small teams. I also have some experience in the following areas: Linux/Unix administration, shell scripting - Bash and Korn shell, Informatica, Perl, Python, C#, software design and testing.  less

    Over the past 7 years I have worked every step of the hardware design process. I have developed requirements, built prototypes, performed extreme environment design analysis, developed and executed verification plans, and worked through integration issues. The projects have ranged from a test PCB design, small ASIC designs, whole chip FPGA designs, individual VHDL components, and integrating a multi-card avionics subsystem for a major spacecraft. If it's electronics or hardware I have your project covered especially if it's FPGA/HDL design. In the course of working I've also picked up the useful skills of several scripting languages, Linux administration, LAN setup and management, SQLite.  less
