Performing software engineering for a variety of customers.

Software Contractor

Founder

Developing software for radiation detection in portals and mobile systems. Custom GTK3 and C# user interfaces. Image processing of moving vehicles. Developing a health monitoring system of remote devices.

Software Engineer

Developing software for an improved MRI spectrometer based on ARM embedded C/C++/Forth, Windows, TCP/IP real time communication, ARM assembly/intrinsics and DSP filtering. Also, developing fee-per-scan invoice generation web application with python and MySQL.

Applications Software Developer

Publishing mobile and desktop apps for facial feature tracking and mobile navigation software.

I was responsible for designing, implementing, integrating and testing software in prototypes of embedded, real time avionics systems. These systems aimed to improve safety and efficiency of aircraft by applying new technology in data communications and displays. I performed: requirements analysis of systems and software software work package planning, provided time and cost estimates, design of high level systems that combined software from other engineers, low level self contained software modules, as well as custom GUIs and displays, debugging and testing of software, liaising between my team and other project partners for system integration, organising and conducting user evaluation interviews, writing technical reports to document findings and preparing and presented project reviews.

Senior Technologist

Instructing students to become proficient in diving, including theory and manual skills. Leading dives, interacting with customers, generally making diving fun!

PADI Master Scuba Diver Trainer

I performed five to eight hours a week on the University computer support help desk. Our mandate was to help students with any difficulties with the public computer systems. I have experience in common packages including Windows, Linux, Office and Paint Shop Pro, etc

IT Helpdesk Operator (Part Time)

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.
