Lead back-end developer for a .NET Core / React web app that helps people decide what to do when they near retirement, for a large UK financial institution.

The application comprises an ASP.NET MVC admin area where the customer service staff would enter basic information about their clients. The client would then log in to the React app, driven by a .NET Core API, which provides content/questions to the client based on previous answers, and includes information such as how long their money would last, tax estimates, etc.

The .NET Core API is driven by JSON data that can be manipulated to configure the journey, for example, to provide different information, questions, or pathways through the application.

I worked as a senior back-end developer on a project for a large UK bank.

The front end was built with React, and I created .NET Core APIs and Azure Functions for the back end. We also created a customer support portal using ASP.NET Core MVC.

One of the requirements was that the app had to handle 2,000 concurrent users, so we used Azure Functions for their scalability and Azure Service Bus so that we could make much of the processing asynchronous.

An important part of the project was the ledger—we had to ensure that no mistakes could be made as we were dealing with large amounts of real money. Code was carefully reviewed, and we created stringent unit tests around all the financial areas so that we could be confident it would work as expected, even under high load.

Another important factor was security, so we implemented Identity Server 4 across the code to ensure that only the correct users could access the relevant functions.

Working via Toptal for an Enterprise level customer, the project was to add features to their Sliicer product which is used to analyze sewer flows.

As part of my work, I implemented Azure Functions and Service Bus Queues to make the application more scalable.

One of the issues I was hired to fix was that their Cosmos DB Documents were growing too large, so I designed and implemented a solution to allow parts of the data to be stored in other Cosmos documents and other parts in Azure Table Storage.

I also restructured their main orchestration layer to make it more efficient and maintainable.

Sole developer on a system to manage licensing of the Perceptor PTXL product.

The licensing web application was built using ASP.NET MVC (.NET 6) and allows administrators to manage the products and features, resellers to create orders, and end-users to customize and place orders.

The system receives usage information from the client installations via Azure Service Bus and Azure Functions. It hosts a .NET 6 REST API that can be used by the client applications to provide usage and licensing information.

The system uses Azure Pipelines for CI/CD.

Lead developer on an ASP.NET Core MVC web application for teachers and parents to register entries for their students for the Big Bang Competition and judging and administration of the competition.

Users log in using Azure Active Directory to enter, judge, moderate, or administer the competition.

This website is linked to the Vision Supplies website and allows users from Intervision Global to easily manage and report on their product database.

It features advanced bill-of-materials functionality for complex projects, allowing them to easily create and manage their bills of materials, including automatic lookup of prices and purchasing functionality.

It also includes multiple web scrapers which are utilised to assist in the maintenance of their 50,000+ products, including product descriptions, attributes, images, files, availability and pricing data.

Working with the team at Concurrent Development as a freelancer, I helped develop and maintain a web application used to monitor fuel, deliveries, and thefts at nationwide petrol stations.

Working with the team at Concurrent Development as a freelancer, I helped develop and maintain a web application used to monitor levels in clothes banks in order to arrange collections and to monitor for thefts.

I built an easy-to-maintain, bespoke CMS for the training course provider, JB International. The system allows the management of pages, blogs, and courses with inline editing so that changes can be seen "in place."
