👋 Hi

I am an independent game developer and the creator of umunki.


After more than 25 years working professionally in software development and civil engineering, I took the plunge in October 2026 and moved into game development full-time.

My particular interest is in making 3D games where curiosity, exploration and intrigue are more important than violence.

I bring a slightly unusual combination of skills to game development: professional software engineering and cloud experience, a background in civil engineering and 3D geometry, several years of learning game development, 3D modelling and digital art in my spare time, and lastly, I'm a musician spending part of my time managing and playing keyboards in Guardians Of The Groove, a Belfast-based Motown, Funk & Disco band.

Software Developer Experience

​​

Azure cloud applications (FaaS):

10 years' experience of Azure Function Apps (Serverless FaaS), Azure Table Storage (Blob, Table, Queue), Azure Signal-R, Azure Cosmos DB.  Re-design of our in-house web-app “DynamicObjects” to run entirely on the Azure serverless platform.

​

Rhino.Compute / Autodesk Forge API:  

10 years' experience with setup /maintenance of Rhino.Compute server on-premises and with using Autodesk’s Forge cloud for the purpose of manipulating parametric geometry files and for boolean union, subtraction, intersection of parts from each other.

​

CI/CD / Azure DevOps:

15 years' experience of Azure DevOps including creating of CI/CD yaml pipelines for continuous deployment of Azure Function Apps from DevOps repos and publishing artefacts to NPM or to private Azure feed.

​

Agile:

15 years' daily practice of Agile principles including daily stand-ups, bi-weekly sprint planning (shippable increments and effort), and sprint reviews.

​

VMs / Server Management / IIS:

5 years' experience with remote admin of Windows Server 2016 VMs (2 webservers, 4 backend workhorses) and setup of DEV, STAGING, PROD servers and installation of services in conjunction with IIS.  Including URL rewrite rules to forward traffic to OWIN self-hosted processes.

​

C# / .NET:  

15 years' daily developing in C# for the Windows .NET environment.  Familiar with NET Framework, NET Core and NET Standard, WinForms, WPF, LINQ, Windows Services, event-driven pattern, object-oriented principles and software design principles (KISS, YAGNI, SOLID etc).

​

Async-Await Pattern / Multithreading:  

Extensive experience with the async-await pattern in C# and familiar with some of the common issues (race conditions, object locking etc).  In addition, have experience of rewriting a single-threaded app to run on multiple specified dedicated threads, managing thread start and thread completion manually rather than using tasks run on the threadpool).

​

VBA:  

10 years' coding in Visual Basic for Applications (VBA) and before that other platform BASICs (Atari, Acorn, BBC), before embracing C#.

​

RESTful API:

Experience extending our existing asp.NET web to include a RESTful api to permit other applications to interact with our app.

​

JavaScript / html:  

Ad-hoc experience of simple JS scripts and html pages mostly in the context of embedding simple webpages within a Windows Form. E.g.to embed an orbitable threeJS 3D model preview pane.

​

SQL:  

Ad-hoc experience in writing SQL queries mainly in the context of writing MS Access (JET) database backend scripts (2006-2010) and more recently with queries sent to the Azure Cosmos DB.  Familiar with general SQL principals such as left / right joins etc.

​

Plugins / Automation:

10+ years' experience of automating MS Excel, Autodesk Inventor and Autodesk Civil3D from external processes using COM and using in-process automation via plugins.

​

3D Geometry:  

10 year's familiarity with 3D geometry concepts and software from working in the domain of 3D geometry and automating various CAD applications.  Including working with nurbs and non-nurbs geometry and working with the underlying breps, meshes, faces, edges, and vertices directly in code.  Also have many hours experience creating 3D models ‘manually’ using Blender for mesh-based models for use in Unity gaming applications, and using Inventor and Rhino for solid-based models for use in infrastructure civil-engineering applications.

​

Unity:  

Scurry! is my current independent game project, built with Unity.  It is a first-person adventure built around exploration, environmental interaction and curiosity rather than combat. 

I am developing the project largely as a one-person studio, covering programming, game design, 3D modelling, character and environment art, UI, audio and the various less glamorous jobs required to turn an idea into a finished game.

Scurry is also my first step towards a longer-term ambition: creating games that make players want to investigate the world around them rather than simply defeat everything in it.

Technology: Unity, C#, Blender, Procreate, GIMP, Audacity.

​

Team leadership:

Experience of leading small team between 2 - 4 developers over many years.  Prior to that, experience as Principal Civil Engineer / Project Manager with similar number or direct reports.
