< What I Do />
Different problems, one idea behind all of them: systems that are predictable, observable, and hard to misconfigure. Whether your team calls it a preflight check, a sanity check, validation, or guardrails, the job is the same: catch the bad state before it ships.
Configuration & Validation
One wrong value shouldn't be able to take down production. I make sure it can't.
See the product →AI Workflow Reliability
AI features that loop, drift, or break silently — made deterministic and traceable.
See the product →Developer Tooling
The fragile manual step everyone dreads, turned into one safe command.
Scientific Software
Research pipelines that give the same answer twice — and that others can reproduce.
Security & Forensics Tooling
After an incident: how it actually happened, traced to the evidence, never guessed.
See the product →Systems Architecture
The failure modes hiding in your system, made visible before they bite.

For small businesses & independent founders
< Founding Client Program />
Testing and validation shouldn’t be a luxury only big teams can afford. So I’ve built an accessible first step: a focused, read-only look at the part of your system most likely to fail quietly — for one clear price, agreed before anything starts.
Starter Reliability Review
£200 fixed
- One small service or pipeline — a slice, not a whole estate
- A read-only pass over its config and structure
- Prioritised findings in plain language, plus one follow-up
Bigger jobs start at £900 read-only and £2,500 hands-on — full breakdown on the services page.
Stay on as a regular client and you keep a standing 25% thank-you — because I want your business to succeed, not just get through this month.

Independent vision · open blueprint
< Social Resource Floor />
A separate, long-term idea of mine held at arm’s length from client work, and open to collaborators.
A floor beneath which no person should fall (My long-term vision)
Human survival should not depend on financial access.
The Social Resource Floor is an open blueprint for a universal structure through which people can access the resources needed for basic survival grounded in being human, not in financial status. It’s designed as a coordination layer above existing social-protection systems like OpenSPP and OpenG2P, not a replacement for them.
At its heart is a dream of a world where every human being has access to the resources they need to survive, live with dignity, and have a meaningful quality of life regardless of their financial circumstances, where they live, or the government and economic systems they happen to exist within.
It’s early-stage and exploratory, which is exactly when extra minds matter most. Contributors from social protection, engineering, policy, or lived experience are welcome.
