  IHS

  Aug 2014 - Sept 2016

  Senior Software Engineer

  I worked at IHS as a senior software engineer for 2 years. I was part of a UK based team, reporting into a large team based in Gdansk, Poland. Our team worked on a large ASP.NET MVC application covering multiple technologies. Our team was just one of 10 sub teams working on the application.As a distributed team, we primarily worked to Scrum/Kanban principles. Key technologies in use were C#, MVC, NHibernate, NServiceBus, StructureMap, MSpecs, RhinoMocks....just to name a few. We designed and wrote our code using SOLID principles and worked in a continuous integration environment.The primary goal of the system was information handling covering many sectors such as automotive, energy, aerospace and economics. My team was primarily involved with Economics & Country Risk, later moving into Healthcare. Show less

  First Databank (FDB) UK

  Sept 2016 - Jul 2018

  Contract Software Engineer

  I am currently working for FDB on a contract basis. A major project that I have been working on has been to help the business move forward with their migration from Accurev over to GIT for their source control. This has involved migrating the code base over to the new system and suggesting suitable branching strategies that they might consider using. I have been heavily involved with bringing their users up to speed on using GIT.Another major part of this project was to migrate their continuous integration system (TeamCity) over to GIT. I have helped to rebuild their TeamCity projects to bring down the processing time and reduce failures. A lot of this work has included optimising tests that have been created in NUnit and Selenium.Other projects have included the creation of a message queuing system using NServiceBus to send reporting data from their public facing web service over to a data warehouse. This web service is hosted within the N3 network and used by healthcare professionals.I have also been involved with creating a new area in their client facing web portal. This has been primarily using ASP.NET MVC and JavaScript. Show less

  LANDMARK INFORMATION GROUP LIMITED

  Aug 2018 - Jun 2019

  Contract Software Engineer

  Key Deliverables:• Maintenance of the Sport England Active Places website. The site is written in ASP.NET MVC 5 with a SQL Server backend. Other key technologies in use are Javascript, NHibernate and SpecFlow.• Addition of new calculation engine for the Sport England Active Places website. The calculator is used to analyse the number of new sports pitches required when the population of a given area is due to increase.• Upgrade of server architecture for the Sport England Active Places website. The platform was upgraded from Windows Server 2008 to Windows Server 2016 and SQL Server 2008 to SQL Server 2017. I was responsible for the installation and configuration of the latest versions of TeamCity and Octopus Deploy. A full CI/CD pipeline was implemented into a new development environment and Octopus Deploy is used to promote builds into further environments.• Large refactor of the Sport England Active Places website. The site comprises of two web front ends and a single database. There were many different mechanisms for connecting to and querying the database and this code was duplicated across both web projects. We split all data access code into a separate project using NHibernate. This project is built, tested and packaged using NuGet on TeamCity. The shared library can then be used across both web projects.• Increase of test coverage across all projects. Most of the projects had some integration tests written with SpecFlow but no valuable unit tests. As we refactored the projects, we introduced a huge amount of unit tests in a standard Given, When, Then format. This has greatly increased the confidence of changes made to the project. Show less
