UK based. Named delivery.
Agents that ship.

Hire a UK-based AI agent developer with 20 years shipping software. Fractional CTO leadership, production-grade engineering, human-in-the-loop by default. Agents wired to your real stack, not demos.


Offshore shops ship code. We ship outcomes.

Most search results for "hire AI agent developer" are offshore development shops or freelance marketplaces. They build the code, then walk away. Here is why UK-based, named delivery is a different proposition.

Offshore dev shops and marketplaces

  • Generic "we build anything" positioning
  • Time-zone misalignment, slow feedback cycles
  • No UK-specific knowledge (VAT, MTD, GDPR nuance)
  • Delivery is code-and-disappear, no ownership of outcomes
  • Churn: the engineer who built it leaves the firm six months in
  • Hard to take a bad outcome to senior leadership with confidence

Digital Signet

  • Named solutions architect with 20 years shipping software
  • London based, UK business hours, same-day feedback
  • UK-specific by default: VAT, MTD, HMRC, GDPR, UK AI Bill
  • Fractional CTO engagement: we own the outcome, not just the code
  • Proven in production: the Xero invoice agent, 300+ AI-built sites
  • Accountable, traceable, referenceable

Agents in production, today.

Agent 01

Xero Invoice Agent

An AI agent built a working app, drafted the proposal for the work, then pushed the invoice to Xero via its API. A human client paid it. Three jobs an employee used to do, done in one session, with a human at the approval gates.

The person you are actually hiring.

Oliver Wakefield-Smith. Solutions architect and engineering lead, London based, 20 years in software. I have been a developer, tech lead, engineering manager, architect, and CTO across media, utilities, satellite communications, engineering, and data transformation. I have worked for and with Thames Water, SES Satellite, Encompass Digital Media, Deltatre, Adidas, the Premier League, and England Rugby.

Digital Signet is the consultancy I founded to combine that engineering experience with AI that can actually build software. The Xero invoice agent, the 300+ content sites, the Bookkeeper, SEO, SDR, Support, Ops, and Recruiter agents you see on this site - those are real, not promised.

When you hire "an AI agent developer" through Digital Signet, you are hiring me. I scope the engagement. I architect the agent. I deliver and hand over. I do not sub out to offshore teams. I do not disappear after handover. The agent runs on your infrastructure, owned by you, with me on call for as long as we agree.


Four engagement shapes.

Agent build (fixed scope)

From £8,000 fixed, 2-4 weeks

One agent, one workflow. We scope, build, pilot, handover. You own the code and infrastructure. Ideal first engagement.

Managed agent (recurring)

From £1,000/month managed

We maintain, monitor, and improve your live agents. Model costs itemised monthly. Monthly tuning session, priority support.

Fractional agent team

£8-15k/month retainer

I embed 1-2 days per week for 3-6 months, building a portfolio of agents across your business. Highest-leverage option for SMBs that want capacity without hiring.

Fractional CTO

From £10k/month

Technical leadership plus hands-on engineering. Architecture, team coaching, process, and agent delivery. See Fractional CTO for details.


Agents that survive past handover.

A working agent

Wired to your real stack, running in production, not a demo.

Human-in-the-loop guardrails

Approval gates on anything consequential, configurable per workflow.

Your code, your infrastructure

Runs in your Azure tenant or your preferred cloud. No lock-in.

Audit trails and kill switch

Every agent action logged. You pull the plug any time.

Runbook and handover docs

Your team can maintain the agent without me, if they want.

UK-specific compliance

VAT, MTD, HMRC, GDPR, UK AI Bill considerations built in from day one.
