Digital Signet is a one-person consultancy backed by twenty years of shipping software across media, utilities, engineering, satellite communications, and data transformation. I build agentic workflows and lead technical transformations for UK SMBs. Based in London, working across the UK and internationally.
I have been a developer, tech lead, engineering manager, architect, and CTO across two decades in software. I have delivered platforms for Thames Water, SES Satellite, Encompass Digital Media, Deltatre, Adidas, the Premier League, England Rugby, and Babcock Engineering. I have scaled teams, modernised legacy platforms, introduced Agile where there was chaos, and shipped across every role a software delivery team has.
In 2025 I stopped taking full-time roles. Not because I stopped enjoying the work, but because AI changed what a single engineer could deliver. I can now build, with a small team and the right tools, what used to take a squad of twelve. The economics of consulting changed with it.
Digital Signet is the consultancy I founded to combine that engineering experience with AI agents that can actually build software. I use it to help UK SMBs ship products faster, modernise their platforms, and adopt AI without over-promising.
The flagship offering is agentic workflows: AI agents wired into the tools your business already uses, doing the work that eats hours but does not need a human to decide. Invoicing, CRM updates, ticket triage, reporting. The Xero story is a real one: an agent I built drafted the proposal for a client's work, pushed the invoice into Xero via its API, and was paid by a human. That is the pattern, productised.
Alongside that I take fractional CTO engagements, AI product builds, and AI opportunity assessments. I also maintain CageClaw, an open-source security sandbox for AI agents, and Signet LLM, a browser-based transformer demo.
Most businesses under £10m revenue cannot justify a full-time CTO, but they still need one. Fractional CTO work fits where the business needs technical leadership without the headcount. I embed for one or two days a week, across three to six months, and build the systems, teams, and products that let the company ship faster after I leave.
The difference with Digital Signet is I do not stop at strategy. I ship code. I have delivered five or more production products in the last year. Most fractional CTOs give you a deck. I give you the deck and the working software.
Engagements are scoped upfront in writing. No retainer creep, no open-ended engagements that cannot be exited. When I build an agent, you own the code, the configs, and the infrastructure. If we part ways, the agent keeps running. No vendor lock-in.
I run everything human-in-the-loop by default. Every agent action worth reviewing goes through an approval gate until you choose to raise autonomy. Audit logs are standard. Kill switches are yours.
I am honest about what AI can and cannot do. If a pilot engagement shows the agent is not the right fit, I will say so and refund the setup if we agreed that upfront. The goal is clients who come back for the next engagement, not clients who regret the first one.
