I am a Data Science technical leader working in algorithm development on Big Data platforms. I have over a decade of experience in leading small teams on both short and multi-year projects, producing bespoke mathematical models and high-performance software for technology demonstrators and operational systems. I have been successful in developing innovative algorithms for a wide variety of applications handling textual, digital signals and imagery data, including a number of patented techniques. I also regularly interact with stakeholders through presentations and written reports, and enjoy learning about new application areas.I have also made contributions to a number of Open-Source Software projects:* Lead developer for 'cryptmount' security tool for Linux* Lead developer for numerical library 'spfpm' for Python* Lead developer for Cygwin download utility 'pmcyg'* Contributor to Debian GNU/Linux operating system* Contributor to the GPSTk C++ library* Contributor to the networkx Python library* Contributor to the Apache Spark projectSpecialities: Mathematical Modelling, Statistical Techniques, Big-Data Analytics, Digital Signal Processing (audio & RF), DSP, Mathematical Computing, Technical Leadership, Applied Research & Development, C++, Scala, Python, Linux.
