Feasibility study for enhanced motion detection of video using machine learning techniques. The objective being to filter out interesting events by discriminating and removing unwanted movement such as rain, foliage movement etc. The study has been made use of the Python based Theano/Lasagne framework on a Linux machine and the Microsoft based CNTK on windows. Initially machine learning basics were studied by completing an online course with Coursera which explored the fundamentals with Octave/Matlab based projects.

Development of a mobile app using Xamarin and a complimentary .Net Core server that is able to collect survey grade geolocation data and integrate with the client's business processes.Responsible for liaising with clients and defining requirements, establishing the system architecture and team leading development. The project was run on an Agile basis using Jira and Confluence.Development of a test suite to verify a SIL 2 rail signalling system.Responsible for architecture of a framework to run and document tests and the test run outcomes. Team lead development of the framework and an extensive set of tests that covered the client’s requirements specification. The system under test was a traditional Windows application with IP message IO. The tests ran at system and major component level and were implemented using C# / NUnit / Test StackWhite. The project was run on an Agile basis using Jira and Confluence.Analysis and visualisation of National Rail data describing the track and signalling infrastructure using Python.Update to a legacy C++ rail signalling application. Creation of tests to prove behaviour before and after update, investigation and correction of long standing bugs in the system and addition of new capability.

Development of Network Rail trackside monitoring equipment. Changed its underlying database from MySql to PostgreSql, taking the update through a formal QA process so it could be deployed with a high level on confidence on the trackside. One challenge with the project was that changes were required in a number of diverse locations in a complex C# codebase. To manage this much emphasis was put on developing unit and subsystem tests to prove equivalent function before and after the change, used NUnit / Justmock for this. Latterly adding in the capability to monitor new equipment types. The project is run using Scrum.

Developed the tool that signalling engineers at National Rail will use to design railway systems across the entire rail network. It integrates a variety of survey and video data into a coherent model of the railway and its trackside equipment. The users of the system can then edit the railway design using a number of visualisations and generate the documentation and specialised exports needed to review and implement changes to the rail network. The application is run within the context of Bentley Microstation which is used to provide the core CAD drawing capability. The core technologies are .Net 4.0, C#, Hibernate, Spring. The project adopted Agile / Scrum based methods. A system of continuous integration was applied using Hudson. A process of Test Driven Development (TDD) was followed using the NUnit framework.

I have helped Innovantage in a number of aspects with their service that provides business intelligence to recruiters and owners of job boards. They maintain a large database of all jobs advertised in the UK from job boards and corporate websites and use this as the basis for reports sold on to their clients.• Creation of a web based reporting mechanism using .net 4.0, Sql Server reporting, ASP, AJAX, paying particular attention to improving the performance of queries over 10s millions of rows. The XML based report definitions are dynamically edited to optimise their layout.• Creation of a Windows Forms application to manage bulk import from text based sources. This provides customised transformations of the input stream, specialised logging and configurable error handling for erroneous input. MS Entity Framework is used to facilitate easy configuration with different data sources.• Provided numerous detailed improvements to their database schema and automated day to day processes.

The Retention People supply a service to monitor people’s attendance at a client’s gym, using this to make statistically based predictions about future attendance and consequential gym subscription. Their technology bias is Linux / MySql and I was used to create a product to integrate with Windows based membership systems which has the following features• A Windows based service installed on the client’s server with a minimal footprint in terms of dependencies and performance loading• Implemented with Dot Net 2.0 with a separate controller application and service communication via a Remoting style interface• Different configurations deployable to integrate with simple file based data sources and fully fledged database systems such as Sql Server.

Development a system to generate fully functional web applications from pre-existing databases without programmer intervention. The premise is that owner’s of databases can lack a suitable interface to access it without recourse to some sort of software development. The proposed system provides a way to get a functional interface at minimal cost. Technically the system is based on MS ASP Dynamic Data using Entity Framework 4.0 to connect to the data source. The system automates the creation of code needed to connect to the database and allows the user to control the details of what is displayed, layout and access.

Creation of a web based property management system using Silverlight. This system presents a map-based view of managed buildings and floor plans within them that provides an intuitive graphical view of the overall region to be managed. Users are able to explore the state of buildings and assets within them, updating them dependant on their level of privilege.Implementation of a major .net 2.0 web application for the Bermuda government sector with over 60 business objects in 50 major pages.

Development of a Silverlight application to present and navigate through complex networks of data using a highly dynamic graphical interface. Development of advanced requirements management tools often using XML Transforms (XSLT) / XSD

Supply and customisation of open source content management systems

Development of a new product range using C++, COM and SQL Server technologies

Updates to a police command and control system based on MS Windows, MFC, C++ clients and SUN UNIX, C, PLSQL, Oracle 8 server

Development of a valuation system for property developers based on Windows / MFC / C++

Managed customisations to a toolset that monitored the performance of mobile phone networks. Responsible for major accounts in the UK and overseas.
