Derbyshire Development Services.

My work across the Derbyshire area 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, 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.

Lets talk about your project, and how I can become a valued member of your team.

MAKE AN ENQUIRY

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.

My Work.

A selection of platforms and systems delivered across CMS, eCommerce, and enterprise .NET environments over the last 25+ years.

Platform Engineering

Built on ASP.NET Core with CMS and eCommerce foundations

All systems are built using ASP.NET Core, typically leveraging platforms such as Umbraco CMS and nopCommerce as a foundation.

Rather than relying on rigid templates or off-the-shelf implementations, I design and extend these platforms to meet specific business, performance, and integration requirements — ensuring each solution is tailored, scalable, and maintainable.

The focus is always on engineering quality, not tooling or surface-level implementation.

Solution Design

Every project begins with understanding requirements, constraints, and long-term goals

I typically work through an architecture-first process — defining system structure, data models, and integration points before implementation begins.

This ensures that design decisions are grounded in how the system will actually function in production, not just how it appears visually.

Once the architecture is defined, development follows a structured delivery process with clear milestones, validation, and iterative refinement through to deployment.

Engineering & Integration Work

Alongside CMS and eCommerce platforms, I also develop reusable SDKs, plugin integrations, and API-focused tooling using modern .NET practices.

Recent public work includes:

• A production-focused .NET payment integration library for Elavon
• A strongly-typed SDK and integration playground for the tado° API
• API abstraction layers and OAuth-based authentication systems
• CI/CD-enabled open-source tooling and integration libraries

These projects reflect the same engineering principles applied throughout my commercial work: maintainability, clarity, scalability, and production reliability.

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 10 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.

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 developer in the Derbyshire area are you’re planning a new CMS or eCommerce build, rebuilding a legacy platform, or require senior engineering input on a complex project, I can help you design and deliver something that will last.

I’m happy to discuss new builds, system improvements, integrations, longer-term consultancy work, or even the possibility of a full-time role.

Who I Work With

I typically work with organisations around Derbyshire where the project is a critical part of how the business operates, not just a marketing asset.

01

Funded Startups & Product Teams

Startups and product teams in and around the Derbyshire area that:

- are moving beyond MVPs and need a robust platform

- require a reliable content and/or commerce foundation

-need senior engineering input without hiring full-time too early

The focus here is getting to a stable, scalable platform that can support rapid growth and a growing internal team.

02

Growing and Established Businesses

Derbyshire businesses that rely on their site for leads, sales, or operations, and need:

- to replace fragile, outdated platforms

- to introduce proper content and commerce workflows

- to improve performance, reliability, and security

- to connect the site with other core systems

These are often SMEs with internal teams who need a senior partner to define and deliver the platform properly.

03

Digital & Creative Agencies

Agencies in the Derbyshire area that need senior .NET engineering support for:

- complex Umbraco or nopCommerce builds

- high-risk migrations and rebuilds

- external system integrations and custom functionality

- technical discovery, architecture, and oversight

I can work as a visible partner or quietly under your brand, helping you deliver technically demanding projects with confidence.
