Hello, I have a BS. in computer engineering from Bar Ilan University a degree which includes both computer science and electrical engineering. Since 2011 I worked for Radware in the Alteon load balancer project, on several topics from layer 2 to layer 7 in the OSI module, I developed protocols such as TCP, UDP, FTP, HTTP, Ethernet, IP, VRRP, DNS. I worked with Linux Embedded real time operating system and C language. and developed software from the BSP level to the higher level and worked a lot with communication protocols. I also have a lot of experience with security, worked with fips level 3 complaint system, Openssl, integrated security hardware and software in the product, also worked on Dnssec implementation. Since April 2008 till 2010 I worked in Motorola Solutions as a Real time embedded engineer in C and C++ languages with communications protocols Vxworks operation system, developing a communication Scada firmware. Worked on developing drivers such has Modbus over TCP/IP, a lot of embedded system security like adding communication encryption using Openssl. user and password communication authentication and authorization while creating a authentication server out of the product. adding XML to the product using LibXML 2.0. and developing processor and BSP software while working with PPC processor. Over the last years I have been developing websites in PHP, SQL, Html, JavaScript, and Ajax, and also in developing WordPress sites. I know how to administrate Linux and Windows servers. I also building website which are search engine friendly so your site will come in the top ten sites in Google and other website as well.

Project:Fix latency issue in PandaBoard ES. Platform:Linux Kernel, RT Preempt, arm/omap4 Language:C Project:Linux Kernel/Networking https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/?qt=author&q=Oussama+Ghorbel Platform:Linux Kernel Language:C Project:USB Driver For Freescale Board Platform:Linux Kernel, GCC, IAR Embedded Workbench Language:C Project:Cache-Forwarding - PPPoE PPPoE is network protocol that allows data communication between two network entities or points. The objective is to enhance the router capability to process PPPoE packets which lead to an enhancement in the WAN throughput. Platform:VxWorks Language:C Project:Cache-Forwarding - Layer 2 Cache-Forwarding - Layer 2 is a service in a router that enhances performance and capacity of bridging. Bridging is a forwarding technique used in network that is based on information located in the packet header . Among the tasks, I made C code optimization based on algorithm optimization and generated assembly code. Platform:VxWorks Language:C Project:Cache-Forwarding - Layer 3 Cache-Forwarding - Layer 3 is a service in a router that enhance performance and capacity in IP packet routing. With this service the throughput has been enhanced from 30 Mbps to 50 Mbps. Platform:VxWorks Language:C Project:Auto-Configuration service This is an embedded application in a router. It allows the router to upgrade the configuration and the operating system using a custom protocol that is based on tftp and ftp. Platform:VxWorks Language:C Project:VRF Implementation That consist of implementing the VRF to different embedded management applications. For server type application; it’s required to create a socket and listen on it for each configured VRF. For client type application, it’s required that the application create a socket and bind it for the configured VRF. Platform:VxWorks Language:C Project:Porting IPV4 applications to IPV6 This consists in porting several embedded management applications from IPV4 to IPV6. The embedded system has two different stacks for IPV4 and IPV6. And therefore the applications must handle sockets separately on each stack. The ported applications are telnet server, telnet client, ssh server, snmp server, http server, syslog server, tacacs client and radius client. Platform:VxWorks Language:C Project:Evolution in some SNMP MIB I added some SNMP MIB modules, with read and write access for different management object of a router device. Developed MIB modules are tacacs, radius, telnet, ssh, syslog, and few others. Platform:VxWorks, Wind River mib compiler Language:C Project:Evolution in network packet analyzer tool The software is embedded packet analyzer tool that can capture and display network IP packets. The evolution was a re-write of the BPF (Berkeley Packet Filter) bytecode compiler to support multiple filters at the same time. Platform:VxWorks Language:C Project:CLI Security Engine Development of a command line security engine that is used by an embedded http server of router equipment. Platform:VxWorks Language:C Project:Blacklist Library The project consists in developing a blacklist library to protect system from dictionary attack. Then the blacklist was implemented on the http-server, telnet and ssh. Platform:VxWorks Language:C Project:Maintenance of Embedded Management System Mainly this consists in fixing bugs and develops new features for a router’s operating system. The OS is based on VxWorks. My task consists in developing things related to embedded management applications and protocols, ex: FTP/TFTP HTTP Server, HTTP Proxy, Telnet Server, Telnet Client Authentication and accounting via TACAS and RADIUS Custom Protocol for auto configuration MIB/SNMP TR069, Data model Platform:VxWorks Language:C Project:Evolution of command line interface engine. The router command line interface (CLI) is based on the rapid control SDK of Wind River. The objective of the evolution is allowing a user to filter the output result of a command, allowing the user to filter lines with several options (include, exclude, begin …). For that a few sub-commands was introduced and they were made available to all routers commands after using the pipe character (Cisco like behavior). Platform:VxWorks Language:C Project:Router’s Web Configuration tool. This project is done for a French telecommunication operator. The project consists in developing a web interface to configure the router through an internet browser. Platform:VxWorks and Web Language:C, JavaScript/HTML Project:OneProvisio This tool helps network operators to manage and edit router configurations and Operating Systems in a fast and error free manner. Platform:Linux Language:PHP, C, shell Project:network equipments supervisor. This tool is used to monitor network equipments that support SNMP. Platform:Linux/Apache Language:PHP, shell

I have more than ten years experience working as software engineer for embedded communication systems manufacturer, mainly programming in C for VxWorks/Linux environment. During my experience I was responsible for design, implementation and support phases of different kind of projects: 1. Communication protocol implementations and applications according IEEE,ITU-T,IETF communication standards or based on MEF specifications Those included. network protocol implementations and support for protocols like STP,MSTP,LACP,LLDP,CFM. Also implementation and support for SSH client for an embedded devices. 2. System level applications like software watchdog, CPU redundancy applications etc. Providing and supporting code that should run on multiple software (Linux/VxWorks) and hardware(Intel/PPC) platforms 3. Often the support and implementation of the communication applications I developed would require interaction with driver/hardware level, so I gained experience supporting and adding features to driver level software for packet processors(Marvel/Broadcom) or FPGAs. During my development activities I have adopted practices as TDD and ATDD, using Test Harnesses for C like cunit, or Ruby's RSpec and Cucumber. For the purposes of imrpoving my TDD practice I developed small ruby tool, called guard-cunit. This and other contributions to open source software can be found at my github profile https://github.com/teacup-on-rockingchair/ Since throught the years I have been in many cases team leader for different projects I gained experience also with introducing and supporting productivity tools like Wiki Web Platform(twiki.org- based) or continuous integration server like Jenkins CI. I am keen on constantly improving my knowledge and experience so I try regularly to take MOOCs, so I have done done Coursera courses on Python, Software Defined Networks and Programming Mobile Apps for Android
