I love what I do.

A Senior .NET Engineer specialising in high-performance eCommerce and CMS systems

Senior .NET Engineer (Full-Stack)

Based in the North East of England, I’m a Senior-level .NET engineer with over 25 years’ experience delivering high-performance web platforms for businesses ranging from start-ups to large international organisations.

My work spans the full lifecycle of modern .NET systems — from architecture and development through to deployment, optimisation, and long-term ownership. I specialise in building scalable, production-grade platforms using C#, ASP.NET Core, SQL Server, and Azure, with a particular focus on eCommerce systems, API-driven applications, and performance-critical environments.

Over the years, I’ve worked with a wide range of organisations including Deloitte, Dulux, AEG, Co-op, Ryobi, SCS Sofas, and Lotus F1 Team, delivering systems that support real-world commercial operations.

My portfolio reflects this breadth — from clean, focused brochure sites through to highly complex, database-driven applications and large-scale eCommerce platforms. A significant proportion of my work is built on ASP.NET, often leveraging Umbraco or nopCommerce as a foundation, then extending and refining those platforms to meet specific business and performance requirements.

Lets Talk.

I’m based in County Durham, near Newcastle upon Tyne, and work with clients across the UK and internationally.

Most of my work is delivered remotely, often as part of long-term engagements or in collaboration with agencies and in-house teams. Whether you need support on an existing platform, performance optimisation, or a new system built from the ground up, I’m available to discuss projects of varying scope and complexity.

What I do.

I design, build, and optimise high-performance .NET platforms - from content-driven websites to complex eCommerce systems

Bespoke Platforms

All systems are built to fit the problem — no templates, no shortcuts. I design and develop tailored solutions aligned to your business requirements, architecture, and long-term goals.

Responsive Web Applications

Modern platforms need to perform across all devices. I build responsive, mobile-first applications that deliver fast, consistent experiences across desktop, tablet, and mobile.

Web & UI Engineering

Clean, usable interfaces backed by solid engineering. I focus on performance, consistency, and usability — ensuring the frontend supports real-world usage at scale.

eCommerce Platforms

Extensive experience delivering and evolving eCommerce systems, from bespoke builds to deeply customised nopCommerce solutions — designed for performance, flexibility, and growth.

Umbraco CMS

Advanced implementation of Umbraco CMS, including custom builds, headless/hybrid architectures, and integrations with APIs and eCommerce platforms.

Application Development

Cross-platform application development using C# and .NET technologies, building integrated systems that extend beyond the browser and connect with core platforms and services.

Trust, Clarity Commitment

Three core principles I bring to every project

With 25+ years delivering production .NET systems, these principles underpin how I design, build, and support platforms for long-term success.

01

Trust

Complex systems require trust — especially when they underpin real business operations.

From initial engagement through to delivery and ongoing optimisation, I focus on clear communication, predictable delivery, and systems that behave reliably in production.

You should always know what’s being built, why it’s being built, and how it will perform in the real world.

02

Clarity

Good engineering should be understandable.

I take an open, practical approach to communication — avoiding unnecessary jargon and focusing on clear explanations of architecture, trade-offs, and implementation decisions.

Whether working on a CMS platform, eCommerce system, or API-driven application, the goal is always the same: make complexity manageable and decisions transparent.

03

Commitment

I work on systems with long-term impact, not short-term output.

That means thinking beyond delivery — into performance, scalability, maintainability, and how a platform evolves over time.

From initial architecture through to optimisation and ongoing support, I stay focused on delivering systems that continue to perform under real-world conditions.

If you’re looking for a senior .NET platform engineer to help design, build, or optimise a CMS or eCommerce system, I’m always open to a conversation..

My clients love the work I produce

After having 3 full website rebuilds in the space of 4 years from different web design agencies which produced disappointing end results and bad service we knew we had to change the type of company we wanted to attempt our next build. We decided to look for a local designer / developer who we hoped could offer everything we ‘thought’ we needed but also suggest ideas beyond our brief and at the same time give advice how to design a better website, that is when we found Craig.

Needless to say the initial brief for Craig wasn’t an easy one as we were looking to re-launch 13 Football Club Online Stores at the same time, all running off one application. However it must have been fate that we were to find Craig for this project as the platform that he uses to build eCommerce sites had just added this functionality and Craig didn’t shy away from the scale of the task. Working closely with Craig and following his guidance we were able to create our own bespoke theme, which for the first time for us was fully responsive for easy tablet and mobile viewing and each theme could be adjusted for each individual store. Craig also solved many issues where the default system couldn’t accommodate our end goal. By the time we came to launch the sites we had a system in place that far surpassed anything we previously had.

That was 7 years ago, since then the sites have continually been upgraded and themes refreshed with new functions added along the way, always striving to make the sites as good as they can be and keeping up with the fast pace changes and expectation of websites in the current digital era.
