SQL and C# ASP.Net core Developer
DAC Beachcroft.
The client is a law firm who are upgrading their core external application to its latest version, for which the SQL database structure has been completely changed. They have dozens of internal apps connected directly to this data; the project involved reconfiguring these to query to the new product; where this wasn't appropriate, new apps were developed to replace them. I contributed to a template for the new ASP.Net core applications, rewrote several of the older apps, made the TSQL stored procedure changes required for most of the others and configured a test server to operate with Azure Devops continuous integration releases. I also created a version of one of the apps in Blazor to demonstrate how the technology could be used to simplify the work of the development team.

C# ASP.Net core Developer
Weston College.
I was brought back to Weston College in order to move their Individual Learner Plan application, and the developer team, from ASP.Net to ASP.Net core MVC. The new development has been managed in Azure Devops with GIT repository. The application's security has been improved by using Azure AD to authenticate users anywhere and on any device, this includes allowing students to invite parents and guardians to the system; via integration with the Microsoft Graph API. The app uses Entity Framework to connect to the internal SQL and Tribal EBS Oracle databases, allowing the college to more easily move to using an EBS SQL database by simply swapping the EF implementation when the time comes. Azure Application Insights is used to log and monitor the app, and several connected services have been integrated using their swagger and WSDL definitions, including EBS updates and AFD postcode lookups.

Senior C# Developer
Lifetime Training.
Working in one of the scrum teams developing Lifetime Training’s in-house solutions for managing their apprentice training business. I made additions to two applications; the WPF app which used SQL replication to allow occasionally connected advisers around the country to sync the details of their trainees, clients and apprenticeships, and the ASP.Net core web app which allowed users to monitor and control the business. In both cases I suggested and implemented improvements to the performance of the apps; by improving data query efficiency and virtualising list displays.

C# ASP.Net Developer
Weston College.
Working in the development team within the IT department. I was taken on to introduce new ASP.Net pages and T-SQL stored procedures to allow the QA department to implement a new tutorial driven process in the existing apps that integrate with Tribal EBS. I completed this while introducing the team to many technologies: Source control with GIT, continuous integration with TeamCity and MS Deploy, these firmer foundations allowed them to migrate their servers to Windows 2016, and the development environment to Visual Studio 2017. Performance monitoring to find inefficient code allowed me to clear up a collation issue in the SQL to Oracle integration that was causing seconds of delay in many queries. I also improved their security model by insisting on the use of https everywhere, and upgrading to the latest version of jQuery.

The main client was written in WPF, where I improved performance of most views by virtualising them. I also helped to migrate the core elements to stand alone Portable Component Libraries, which were then used as the basis of an iOS and an Android implementation of the app using Xamarin.

Avelo.
In the Wealth Management team helping to produce a PoS, Point of Sale, case management application for client facing Financial Advisers.
This ASP MVC web-based application can run on an IIS server in the usual way, or be installed on a laptop running IIS express connecting to a local SQL server. This allows Advisers to work on quote and sales details whilst meeting customers, in an offline mode. Later on, changes to the data are synchronised to the central servers when the adviser laptop is back online.
I developed pages from the backlog using C# MVC and jQuery, as well as introducing Specflow and BDD to the team in order to improve their agile processes and build quality.

.Net Developer
Parliament.
In a small team within the Parliamentary ICT service. We produced 3 ASP.Net MVC / jQuery based applications to be viewed on mobile phones.
The first application linked with the annunciator service to display business in progress in the Houses. Another linked to a CRM system from third party consultancy LBi to display pages from the intranet. Finally, we produced a detailed interactive map of the Houses based on my own bespoke GIS system.
Using a novel MVC view engine to deliver different CSS and javascript to different clients allowed support for a range of mobile devices, from very restricted Blackberries to iPhones.

Analyst Programmer
OD2.
I provided architecture and development services for Europe's leading music service; used by Tiscali, Coca Cola and MSN.
OD2's client application was only provided in English, I developed a replacement that updated its translations over the web and styled itself to match the web site that the user was shopping.
This formed a core part of SonicSelector, a client application that integrated with Windows Media Player to provide a complete music experience. I designed and developed the purchase and transfer functions that offered users a single process to buy tracks then download and burn them to CD. Skills VB6, COM
I worked with another architect to produce the media bar ActiveX control that provided in-page playlist, playback and download of tracks from the OD2 run websites in IE, Windows Media Player on PC and in Windows Media Centre. The core was in VC++ and the presentation layer was a VB6 ActiveX COM Component.
