Senior-led Umbraco development. No juniors, no account managers.
The person who scopes your project is the person who builds it. Simon Antony is a senior-led Umbraco team: every project gets direct access to the architect who designed it, with no junior handoff after the sales call and no account manager in between.
That matters because of what Umbraco is. It's an open-source CMS built on Microsoft's ASP.NET Core framework with no plugin marketplace; every feature is custom-coded in C#, which means implementation quality depends entirely on the developer's expertise.
The work speaks for itself. We are an Umbraco Silver Partner, one of fewer than 150 worldwide, led by Simon Steed, Umbraco MVP 2026, and we've delivered Umbraco solutions across every major version from v4 through v17 for organisations including the British Red Cross, the Scottish NHS, and Vodafone.
What you get.
Generalist agencies typically treat Umbraco as just another CMS. But Umbraco's architecture, custom C# controllers, Razor views, and a composition-based content model, requires deep platform knowledge to implement properly. A poorly architected Umbraco site is harder to rescue than a poorly built WordPress site because there are no plugins to fall back on.
Working with a specialist means your project is built on proven architectural patterns from day one. Our builds consistently achieve Lighthouse performance scores above 90, with clients averaging a 40% improvement in Core Web Vitals within 30 days of launch. We handle the full stack: custom document types, API integrations, Azure deployment pipelines, Cloudflare edge configuration, and ongoing retainer support.
Every project gets direct access to the architect who designed it, there's no junior handoff after the sales call. That's the advantage of a senior-led, three-person team over a large agency.
Senior Umbraco development, by the hour.
One rate, no tiers of seniority to decode. The person who scopes your project is the person who builds it.
- Senior developers only, no juniors
- White label available for agencies
- Direct access to the architect who designed your build
- No account managers in between
Who has Simon Antony built Umbraco sites for?
Since 2008, we've delivered more than 200 Umbraco sites across sectors including healthcare, charity, telecoms, recruitment, marine science, and professional services. Our client portfolio includes the British Red Cross first aid training platform, Scottish NHS iHub, Vodafone (via Yes Telecom infrastructure integration), and specialist firms like Translation People and Compliance Insider.
We operate as both a direct agency and a white-label development partner for other agencies who need senior Umbraco expertise without hiring in-house. Approximately 40% of our work comes through agency partnerships where we build the technical solution while the partner manages the client relationship.
Our project types range from greenfield Umbraco builds and complex legacy migrations to ongoing retainer support and performance rescue engagements. Most retainer clients have been with us for over three years, which we believe says more about our work than any sales pitch.
“My colleagues and I worked with Simon as our principal contact at YesTelecom; we found him to be great guy to work with - he 'got' what we were talking about instantly and always pulled the stops out to make sure we met mutual deadlines. I wouldnt have any hesitation what so ever of recommending him to anyone else and i look forward to working with him on other projects”

What do clients say about working with Simon Antony?
We've worked with organisations ranging from the British Red Cross and the Scottish NHS to specialist recruitment firms and marine science bodies. Our client relationships typically span multiple years. Most of our retainer clients have been with us for over three years, which we believe says more about our work than any sales pitch.
Client feedback consistently highlights three things: we communicate clearly without jargon, we deliver on time, and we're honest about what a project actually needs rather than upselling unnecessary work. As a small, senior-led team, every project gets direct access to the architect who built it, there's no junior handoff after the sales call.
We're happy to provide references and case studies on request. You can also see examples of our work in our portfolio.
“Simon completed a contract with a key client, and throughout the process was a pleasure to work with. Both Simon's technical skills and personality will prove to be a great asset to any business either in a long-term permanent role or whilst providing consultancy services on an interim basis.”
