What I do

Fixed-scope technical engagements. I go into systems, find what's wrong, and tell you exactly what to do about it. Written report. No retainer.

Based in Mallorca and the UK. Working with clients remotely worldwide.

AI & Agent Production Audit

AI-assisted builds look convincing. They're not always solid. Before you go live with a system handling sensitive data, real users, or business-critical workflows - find out what you actually have. I review architecture, security, data handling, authentication, integration points, and load behaviour. You get a clear verdict: what's ready, what isn't, and what to fix before you ship.

Good fit for

  • Systems built by an external team or AI-assisted agency that you need to validate before go-live
  • Anything handling sensitive data, financial transactions, or user-facing workflows
  • Teams who need an independent read before signing off on an external build
  • Companies in regulated industries who need documented assurance before deployment

Clarity Audit

From £3,500

Know exactly what's broken before you go live. Security review, architecture spot-check, and a dependency vulnerability scan - for smaller builds and MVPs.

Good for

  • MVPs and internal tools
  • AI-assisted codebases
  • Early-stage products

12–18 page written report with fix recommendations and a 45-minute walkthrough call.

Production Audit

From £6,500

Production-ready sign-off with a roadmap your team can execute. Full security, architecture, infrastructure, and data-handling review.

Good for

  • Builds handling real users or payments
  • External or AI-assisted builds going live
  • Post-delivery vendor validation

20–25 page report with developer-ready fix specs and a phased remediation roadmap.

Regulated & Investor-Ready

From £9,500

Senior technical sign-off for regulated industries and investor due diligence, including compliance mapping and a production readiness scorecard.

Good for

  • FinTech, HealthTech, LegalTech builds
  • Pre-investment technical assessment
  • Complex, multi-repo systems

25–35 page full report plus an executive summary written for investors and the board.

I've run production-readiness audits under GS007 financial assurance standards at Dexus (ASX-listed, ~$50B+ in assets) and data integrity investigations for agriculture SaaS platforms. Most recently, short-engagement go-live audits for AI-assisted codebases.

Scope depends on codebase size and system complexity. Every engagement starts with a free 30-minute call - I'll tell you whether it fits and what I'd need to review it properly.

System Diagnostic & Remediation

Something's wrong and nobody can pin it down. Data going missing. Events misfiring. Performance degrading in ways nobody can explain. I come in, go through the logs, trace the failure patterns, and find it. Some issues I fix directly; others I document precisely for your team. Either way, you stop guessing.

Good fit for

  • Data integrity issues - records inconsistent, writes going missing, conflicts you can't trace
  • Event-driven systems with silent failures nobody can reproduce reliably
  • Third-party integrations misfiring in ways the vendor can't explain
  • Performance degrading gradually with no clear cause

How it works

1

Triage call

You describe what you're seeing. I ask the questions that tell me where to look first.

2

Investigation

I go in - logs, architecture, execution traces, the works. No assumptions, no guessing.

3

Findings report

Root cause identified, failure chain mapped, priority fixes documented.

4

Remediation

Direct fixes where I can deliver them cleanly. Precise handover documentation where the fix belongs to your team.

Diagnosed and resolved a critical data integrity crisis for an agriculture SaaS platform - DynamoDB inconsistencies, cross-application conflicts, lost records. Investigated via logs, implemented optimistic locking, fixed GraphQL mutations, built Python reconciliation scripts.

Diagnostic engagements are scoped after the triage call - complexity varies too much to price blind. Most run 1–2 weeks from £6,000.

Technical Due Diligence

Before you write the cheque. Architecture, code quality, security posture, technical debt, team capability, infrastructure - everything an investor or acquirer needs to know before committing. Written for both technical readers and the people making the investment decision.

Good fit for

  • Investors evaluating a target before signing
  • Acquirers who need independent technical assessment
  • Founders preparing for due diligence who want to know what an investor will find
  • Post-acquisition - you've bought something, now you need to know what you actually have

Final price depends on company stage, codebase size, and report requirements. Every engagement starts with a scoping call.

Technical audit and compliance assessment at Dexus (ASX-listed, ~$50B+ in assets) - governed under GS007 financial assurance standards. Full architecture, code, and operational risk review.

Architecture & Build

For situations where diagnosis alone isn't enough - where the right call is to fix it, build it right, or rebuild from a clean foundation. Fixed-scope delivery, defined outcome, senior hands throughout.

Good fit for

  • Post-audit remediation where the fix requires building, not just documenting
  • Greenfield architecture for teams who need the technical decisions made correctly before they start
  • Critical path unblocking - 2–4 week sprint to get a stalled project moving again

Rescued a .NET migration six months overdue at Lancom Technology - back to billable within a month. Zero-to-pre-seed SaaS build, architecture through to MVP delivery.
