Act 01 of 04
Isolate
Find the one place the work gets stuck.
AI Product Builder & Forward Deployed Engineer
Find where the work gets stuck, build AI-native products and workflows that fix it, and deploy them inside organisations with approvals and guardrails built in.
Have a process to automate, or an AI system that needs proper governance and observability? Glad to talk.

Directed four products, each with a stage stated plainly. Nothing released without approval.
A process fails in one place first
Everything looks slow from outside. Usually one handoff, approval or manual task holds up the rest. Finding it is most of the work.
Start with the stuck point
Where does work wait? Which step is always manual? Who chases whom? Writing the answer as a testable problem before anything is built.
Act 02 of 04
Trace
Follow the fix from objective to approval, one stage at a time.
Stage 1
Objective and context
Defining the objective and supplying the context. A build that starts without both is guesswork.
Stage 2
Break it into stages
Big tasks split into clear stages: research, data processing, drafting and checks. They connect through APIs, MCP servers and RAG.
Stage 3
Review apart from building
Code is reviewed, evaluated and tested separately from the build, with a human in the loop. CI runs before release.
SpecifiedLogging shows what ran, what changed and who approved it.
Stage 4
A person signs
Human gateNothing is published, sent or paid for without approval, and every claim must be backed by evidence.
How a build is governed
The method, in full
Treating each build as a governed process: development, observability, and forward deployed engineering once live.
Development is agentic, runs through APIs, integrations, MCP servers and RAG for source-based tasks. Each with a defined role, coordinated by an orchestrating step.
SpecifiedLogging shows what ran, what changed and who approved it.
Governance built in: your data stays local, and every change is logged, approved and traceable.
Act 03 of 04
Release
Put it to work where the work is.
Built for Reality, Not Demos
Deploys securely within your actual infrastructure, processing real data under your existing business rules.
Forward-Deployed Optimization
Deployment is just day one. Continuous lifecycle support ensures the system is actively monitored, maintained, and refined directly within the production environment.
Built-In Guardrails
Data handling, approvals, and guardrails are hardcoded before any workflow runs. Every change is verified, logged, and blocked from release until explicitly approved.
What can be done for you
From the stuck point to something running
AI-native products
Directed products from objective through to a reviewed result. Shipped this way: PitchReach, AMLtracker and the Global Investor Guide.
Business automation
Workflows for the routine steps of a business.
- Missed-call and enquiry follow-up
- Lead capture and CRM sync
- Appointment booking and reminders
- Invoice, quote and payment chasing
- Document and data extraction
- Scheduled reporting
Scalable autonomous workflows
Work is split into stages, with a person setting the objective and checking the result.
Orchestration frameworks
Several steps are coordinated so each handoff stays explicit.
Forward-deployed integrations
A live system is connected in place, then watched and corrected after it ships.
Governance and guardrails
Data handling, approvals and guardrails are set before a workflow runs. A change is checked and logged, and it does not go out without approval.
Case study
TextBackCaller
LiveAI-assisted automation, end to end: from a missed call to a text back, with a person deciding at the points that matter.
ShippedA missed-call text-back service. Live, launched 19 October 2026.
ShippedFor UK small businesses.
ShippedCustomers keep their existing business number.
The automation
Once, when a customer signs up
- 1Customer signs up and pays by cardStripe Checkout
- 2A signed payment webhook starts provisioningCloudflare Worker
- 3A UK mobile number is bought for the customerTwilio API
- 4Setup text and setup email go outTwilio SMS, Resend
- !If setup fails or a trial is refused, the owner is alerted and a person decidesHuman gate
Every missed call
- 1The phone network diverts the missed call to the customer's numberConditional forwarding
- 2A signed webhook arrives; the call is rejected as busy at onceWorker, Twilio voice
- 3Guards are checked, then one text goes to the caller from the business's own numberTwilio SMS, D1
ShippedOne text per caller per 24 hours, UK mobile numbers only, and the owner's own calls are skipped.
ShippedSignup, payment, number provisioning and setup messages run automatically, with no manual step between a paid signup and a working service.
Tools called
| Service | Called for |
|---|---|
| Stripe Checkout and Billing | Taking the subscription; signed payment webhooks back |
| Twilio Voice and SMS | Buying numbers, receiving missed-call webhooks, sending the text |
| Cloudflare Workers | Running the logic, with a scheduled job each hour |
| Cloudflare D1 | Signups, customers, usage, opt-outs |
| Resend | Setup and alert emails |
ShippedEach service is called through its API: Twilio for voice and SMS, Stripe for checkout and billing, Resend for email, D1 for storage.
ShippedBuilt on Cloudflare Workers, D1, Twilio Voice and SMS, Stripe Checkout and Billing, and Resend.

Built as AI-assisted automation
ShippedBuilt as AI-assisted automation: AI workers implement each staged release and call tools through APIs and connectors. Reviewed the evidence and approved.
Where a person decides
Human gateEvery release needs approval. Builds are staged, tested, backed up and given a rollback point first.
Human gateNew features ship switched off. They are switched on in a separate, approved change, and a kill switch turns each one off again.
Human gateWhen automatic setup fails or a trial is refused, the owner is alerted so a person decides what happens next.
ShippedRelease controls: signed webhooks, duplicate-send prevention, opt-outs, usage caps and automated tests.
