I'm a computer scientist with a strong focus on software and systems engineering, specialising in C, C++, and C# with deep experience in the Windows API and Windows Kernel development. My work spans both low-level systems programming and high-level application design, integrating performance, reliability, and maintainability.

I also have extensive experience with Identity and Access Management (IAM) technologies and standards, including SAML, SCIM, and WS-Federation/WS-Trust, applying them to build secure and scalable authentication systems.

Throughout my career, I’ve worked across the full software lifecycle, adopting Agile practices, UI/UX design, and modern DevOps principles. I’m passionate about performance optimisation, scalable architectures, security, and accessibility, and enjoy exploring new concepts and technologies.

I am currently a software engineer at consumer finance company Wealthify, and Director at technology company SharpVNC Limited.

Some of my recent projects are listed below:

• Windows Filtering Platform (WFP) drivers - mouse & keyboard Windows Kernel filter drivers, used for input interception at a hardware level.
• SharpVNC - a .NET client & server implementation of the Remote Framebuffer Protocol (RFB). This will now be licensed proprietary for binary distributions only. SharpVNC remains the exclusive intellectual property of SharpVNC Limited (reg. number 14907913).
• Mirror Driver - Windows 2000 Display Driver Model (XDDM) mirror driver for the Graphics Device Interface (GDI) - written in C using WDK. In line with industry conventions, this is licensed proprietary for both binary and source distributions. SharpVNC remains the exclusive intellectual property of SharpVNC Limited (reg. number 14907913).
• Mouse & Keyboard Filter Drivers - Mouse & keyboard filter drivers for the Windows kernel, enabling low-level interception and manipulation of user input, using the Windows Filtering Platform (WFP).
• Windows Credential Provider - a .NET Framework implementation for use in Windows 7 and above.
• Better Controls - a .NET 6 library that provides comprehensive wrappers of certain Windows API controls, where either the built-in wrappers are limited in functionality, or wrappers were never provided. These controls include Toolbar and Rebar, with full .NET 6 design-time support using the new client-server design-time bridge model.

Some of my other projects that are typically not feature complete, or don't intend to be finished, are listed below:

• ASP .NET Core - Meter Readings (Interview Task) - an interview task to provide an API interface to accept electricity/gas meter readings and persist to database. This task assumed part of a wider, more complete project.
• DapperExtensions - SQL - a small library written in C# that provides automatic & dynamic SQL query generation and where expressions around the Dapper ORM.
• Win32 GUI Calculator - intended to be a simple Win32 GUI calculator written in C++, but so far just various window creation routines.
• GDI Drawing - a .NET wrapper of the Graphics Device Interface (GDI) to enable high-performance, hardware accelerated drawing operations.
• .NET 6 Component Licensing - Replacement for .NET Framework's legacy component licensing infrastructure (which was not completely ported to .NET Core), which leverages the requirement that custom components must be distributed using NuGet.

During university, I worked on a number of industry projects that formed part of the assessment. Some of these are listed below:

• Ambulatory Care - Written in React Native and Java. This was a University industry project in a team of 5 working for the NHS to create a mobile application to aid cancer patients administering chemotherapy treatment from their home. It allowed for remote monitoring by doctors and other interactions.
