I started using Python for image processing during my PhD in computer vision/machine learning, gaining extensive experience with Numpy and Scipy. I have since completed several web based projects using Pyramid/Django. I have contributed to multiple open source libraries including scikit-learn, scikit-image, python-oauth2. I am currently porting django-oauth-plus to Python3/Django 2.0. I released a game "That Untravelled World" on Android/Windows/Linux eventually publishing it as open source (see kinatomic.com). Python is my current "go to" language and often write python extensions in C++ when performance increases are required.

I learned C++ on the job in an embedded real-time avionics company (BAE Systems). I have been using it regularly since 2001, particularly for any task in which performance is critical. I have completed many embedded (ARM processor and Intel) and GUI projects (GTK+ and QT). I have used C++ to extend python which high performance is needed using SWIG. I have instructed third year undergrad/masters students in software labs at the University of Surrey. I have used OpenCV extensively for image processing and I repackage recent versions for Ubuntu here https://launchpad.net/~timsc I contribute to several open source projects on github including tilemaker, ORB_SLAM2 and libpqxx.

I started learning C in 1997. I have extensive experience of C in embedded systems, often using it's functional style as a compliment to C++, particularly for low level IO. I have instructed first year undergrad students in software labs at the University of Surrey in the use of C. I recently released iso8601lib for date/time processing on github.

My PhD thesis was titled "On the Automatic Recognition of Facial Non-verbal Communication Meaning in Informal, Spontaneous Conversation" which gave me experience in object tracking, classification and regression methods (SVM, SVR, Boost, Decision Trees, etc) and common image processing methods. My approach also used crowd sourced data from Mechanical Turk/Crowdflower.

Since databases are essential for almost any web app, I have experience in relational database schema design, query optimization, indexing for huge tables (hundreds of millions of rows) and geospatial data.

I am a heavy user of Git and Github. While the learning curve is steep, it is excellent for both conventional teams and loosely affiliated collaborators.
