Cloud platform development using Microsoft Azure, creating services to handle product and pricing information and quoting. Multiple systems require pricing information and there are a number of different solutions being used. The design of this set of services is to have one solution that every application uses.Created the design and architecture for the services using Microservice Architecture with Service Fabric and Azure Functions. This presented an interesting challenge as the infrastructure is maintained by a separate team in a different location.Trying to influence DevOps and Agile working practices alongside the Scrum Master to allow better ways of working. Encouraging the team to do more pair programming/mobbing and work towards becoming a cross functional, self-organising team.Applications and Infrastructure as code are all deployed using Azure DevOps (formally VSTS), once code has been approved then it is automatically rolled out into our Dev/Test environment and runs the Integration test suite.Member of the Cloud guild, aligning the vision of moving applications to the cloud and defining guidance for all development teams.Taking advantage of the latest C# features and .NET Core 2.x.Migration of Application to .NET Core 3.1 (December 2019)Azure Table/Blob StorageAzure Virtual NetworksAzure ApplicationInsightsARM TemplatesPowershellGit source controlUnit testing with xUnit/NUnit and NSubstituteIntegration testing with BDD framework Specflow and Postman CollectionsVisual Studio 2017/2019 Enterprise with ResharperRunning workshops on TDD, Specflow, Azure Functions and ARM templates

Cloud platform development and architecture using Microsoft Azure, creating services to take requests from and push notification to thousands of devices. The devices utilise the Android OS but are not Google certified which provides an interesting challenge to the Notification platform. The platform takes advantage of Microservice Architecture in order to deploy parts of the infrastructure independently and decouple the system logic.There is also integration with the Broadworks Broadsoft Platform via OCI and XSI events and actions to retrieve events from the PBX e.g. Do Not Disturb, Call Park and Retrieve as well as requesting information from the PBX.Created the design and architecture for the notifications to accommodate the next device that would be Google certified, to take input from the Broadworks platform and send notifications via Azure Functions, Azure Notification Hub and Google Firebase.The deployment pipeline is managed by TeamCity and Octopus Deploy to easily manage the many parts of the server architecture which has a mixture of Windows Services, Service Fabric Services and Web Apps.Monitor production applications and react to issues as they occur in order to fix issues quickly.Encouraging the team to become a self organised DevOps team.C# 6/7 (Visual Studio 2015/2017 Professional with Resharper/DotCover).NET Core 1.x and 2.xASP.NET Core MVC/WebAPIUnit testing with xUnit/NUnit and NSubstitute/MOQLog4net/Serilog with Application Insights and RaygunIntegration testing with BDD framework SpecflowMaintaining builds in TeamCity and deployments in Octopus DeployAzure Service Fabric (Microservices)Azure Web AppsAzure Functions (Serverless/Nano-service Architecture)Azure Table/Blob StorageAzure Service Bus/Event HubAzure ApplicationInsightsAzure Notification HubAzure Cosmos DBARM TemplatesPowershellAgile - Scrum for teams with the SAFe Agile Framework

This role was part of an architecture team designed to provide expertise from many rather than a single architect. I was able to start influencing a move to use distributed source control (Git), improve the BDD testing and looking at a more SaaS architecture where possible. Also looking at DevOps and seeing how we could benefit from this.Most of my time in this role was design and implementing RESTful services to create simple API's to allow easy interaction between parts of the system and lightweight Angularjs 1.x clients for users.

Working on Bespoke software for Exxon Mobil, adding new features and maintaining the Loyalty Platform. This involved working with code written in a variety of languages and frameworks. Some of the legacy applications were in C and classic ASP.The most noted projects I worked on were:• Tesco – Integrating the Loyalty Platform with Tesco Clubcard, making it possible for Esso petrol stations to give customers clubcard points when they buy fuel. This project involved liaising with Exxon and Tesco including developers in India. Whilst the project was worked on by a team in the beginning, by the end I was the sole developer and oversaw the release to production and supported the initial pilot roll out. All the code was written in C# and using Dapper micro ORM for the database interaction.• Hardware Refresh – Upgrading the Loyalty Platform hardware and software solutions. Moving from Windows 2003 server to Windows 2012, SQL Server 2000/2008 to SQL Server 2012. This included upgrading a classic ASP management website to ASP.NET MVC 4/5. The website was a layer over the database to allow our customer (Exxon) to self-manage the configuration of the Loyalty Platform.I also maintained a number of applications used by the development team:• SVN (Subversion) source control server, updating to the latest SVN and patching the server• Atlassian Crucible – Code Review Server• Jetbrains TeamCity – CI/CD server• Media Wiki – Wiki server to host the development documentationThe rest of this role was mentoring developers in use of the technologies and frameworks used in the platform and encourage working with Agile (Scrum, Kanban), TDD and BDD, becoming self-organising teams and using code sharing via package feeds e.g. NPM, Nuget (even setup in-house nuget packages via TeamCity nuget feed).I was also able to continue working with UI design for some of the websites with Balsamiq Mock Ups and promoting the need for good UX.
