• My role within the Threatmetrix Device Intelligence team involves developing software for the purpose of capturing information from within our delivery vectors and to manage that data collection as it comes in, with.
• Working within apache module devel, tomcat for business logic, Linux daemons and client OS targets via an sdk in the applications supply chain.
• Obfuscation of all operations and data, implementations and over the wire interactions to reduce bad actor countermeasure development and reduce client interaction requirements to keep friction in the security vs.
• Constant information gathering development in environments, which are constantly changing, hardening and increasing in obfuscation themselves.
• Developing Anti fraudster detection improvements while operating from inside client deployments within the limitations imposed by modern sandboxing technologies.

• Primarily the role entails full SDLC adherence and utilisation to deliver red team software involving both kernel and user space development for the purposes of BT and its customer’s security concerns from within BT.
• Extensive knowledge of the Linux kernel, developing for the Linux kernel in C99, the Linux networking stack and userspace processes.
• Development of userspace applications primarily in C++17 and python 2.7 for various flavours of Windows and Linux.
• Developing test tooling to monitor, penetrate and protect attack surfaces within BT and their customers deployed systems, applications and infrastructure.
• A dedicated development house geared towards R’n’D, Requirements capture, Generating POC’s, design and design documentation, testing and associated documentation, generating the implementation while observing a full.
• Developing tooling for automated testing. Applying testing to all feasible levels of development, unit, feature, SIT, UAT and regression testing. If it isn’t tested working, it does not work, as an ethos.

Primarily the development and maintenance of the calculation engine written in C++ utilizing Boost and QuantLib. The engine is capable of stochastic model generation and simpler file inputs assuming the input contract is honored.The engine is primarily supplied in the form of a lib which is capable of being wrapped in multiple delivery methods, currently.

• Second year: RuzzTv team, ApplicationsA large parallel processing environment largely responsible for managing material throughout the television factory, operating and integrating with various physical workflows and.
• Worked on maintaining a large code base predominantly in C++ (mix of languages and technologies) with quite allot of domain specific knowledge. Heavily involved with SQL (The solution largely functions and coordinates.
• Involved in a large overarching project porting from QNX to a Linux ( Red Hat ) substrate for the entire eco system of Ruzz technologies.
• A Large mature parallel processing system with relatively little documentation requiring a great deal of communication with staff. This level of communication created an opportunity to become much more skilled in.
• Actively participated in fault finding, bug resolution for complex race conditions inherent in a largely parallel environment, fixes and general changes required by an in use evolving system as the clients required.
• Given tasks in performing additions to facilitate new client requirements.

• First year: OpenTV, OS and Middleware development teamA head end, playout and set top box operating system and middleware manufacturer, my role encompassed working with the local implementation of the OS and Middleware.
• Created a working prototype of the DSMCC integrated OS used for testing and initial deployment build design. Used to proof function, fit for purpose and analysis of throughput numbers.
• To facilitate my function within the role I had learned allot of domain specific knowledge, local television broadcasting standards (DVB), a new large code base and threaded infrastructure Exclusively in ANSI C.
• Analyzed hashing algorithm collision issues through a mathematical proof and produced domain specific data, analyzed performance issues and produced reporting to management.
• Generated some associated test tools in C++, scripts in bash, python and awk(perl-ish) to analyze traces for test result analysis.
• Took an active part in the construction of the test environment, which involved understanding DVB and low level MPEG, the transmission of television broadcast signals from a lower level through to the tested device.

I primarily worked on porting a warning, command and control system for Telstra's SMS infrastructure from pre c89 code to c++03 which involved an architectural change from a procedural model to an OO model. I cannot say enough positive things about the work environment provided and the caliber of the people I worked with during my time with Protocom.
