Arootz develops a multicast to storage distribution network with a current focus on video. My core responsibility is to develop the multicast congestion control algorithms and also be part of the team that develops the whole network distribution software from the content provider to the client PC. The software is developed to be cross-platform in C++ using ACE. The development is done on Linux and the client is tested on both Linux and Windows.

Tested the behaviour of the Linux kernel in high bandwidth-delay product networks (e.g. high speed trans-atlantic networks) and improved the performance to be able to fully saturate a 1Gbps link. Maintained patches of the H-TCP congestion control and had them accepted to the Linux kernel.

Shunra develops a network emulation appliance based on Linux. I was a Linux kernel expert, extending the abilities of the product with additional features in the complete path from the user-mode configuration down to the kernel level emulation of complex network behaviour.

In addition I helped improving the development environment by introducing KGDB, improving build scripts and raising suggestions for process improvement.

Jungo develops OpenRG, a Linux and VxWorks based software stack for broadband modems and routers. I was the component owner of the Firewall and NAT module in OpenRG. My responsibility was to design and develop the firewall, improving it to fit increasing requirements and overseeing developers who helped with design and coding. Development in the kernel for the filtering itself and user-mode for Firewall Policy configuration. During this work I learned a lot about Networking (IPv4, TCP, UDP, PPP), Linux kernel internals, as well as proper Software Engineering.

Developed dynamic web-sites with MySQL as the database and PHP as the implementation language. The work included, design, implementation and support and required interfacing with a legacy Magic database. During this work I learned about Relational Databases, SQL, PHP and database-driven website development.

Developed Perl modules to perform screen-scraping of e-commerce web-sites such as Amazon to track prices and enable one-click purchase from within the application without the need to go through multiple web-pages. Learned Perl, HTML & HTTP.

Developed an MPEG-1 System layer decoder, with emphasize on resilience to transmission errors. Also helped fellow lab members with their tasks. Worked with C++ & STL.
