implemented a lossless compressor of filesystem metadata transforms, reducing the impact of a significant AeroFS architecture bottleneck (Java, Docker)

iterated on the code and infrastructure for a large Ruby on Rails app

built various core AeroFS and Redbooth microservices (Golang, Java, Docker)

wrote C++ code on a BSD-based controller responsible for compiling high level filter expressions into ultra high speed content addressable memory (TCAM) keys, allowing for sophisticated filtering to occur at line rate

developed microcode for the Tilera NP5 network processing chip matching all incoming packets against TCAM keys, sending matching packets to the capture devices

built their product's network neighbour discovery system, including a custom implementation of the proprietary CDP (Cisco Discovery Protocol) (Python)

wrote the code which enabled live and partial networking reconfiguration of their product (previously the networking controller had to be restarted for configuration to take effect) - which included significant changes to the real-time packet processing system that ran on an Arista switch (Python, C)

forked and iterated on a high performance media streaming server, adding new network protocols and making changes to others (C++)

made significant changes to the test automation infrastructure (Python, MySQL) to support the operation of the traffic generator and statistic collection
