Interim CTO · Technology turnaround
Modernise the stack — and pass the audit — without freezing the roadmap.
I step into companies mid-turnaround and take legacy debt off the critical path: off the monolith, the compliance gaps auditors flag closed, and AI added only where it moves a number. I took my own company from pentest findings to ISO 27001 and SOC 2 Type 2 certification in about three months, without pausing delivery. Then I hand you a team that runs it without me.

The first 90 days
A plan that assembles itself.
Not a discovery phase that never ends. A dated path from "we're not sure what's on fire" to "the team owns it" — the same path I ran at my own company, from pentest findings to ISO 27001 and SOC 2 Type 2, in about three months.
- Week 1
Risk & architecture read
I map the monolith, the dependency graph and the gaps auditors will flag. You get the real picture — not the org chart.
- Weeks 2–4
Standards & CI/CD quality gates live
Automated quality gates, security baselines and a working path off the critical dependencies. The team keeps shipping.
- Weeks 5–8
Measurable wins + a board-ready roadmap
Legacy debt moves off the critical path, one metric moves, and the board gets a roadmap they can fund.
- Handover
A team that runs it without me
Ownership stays inside the company. A clear end, not an open-ended arrangement.
How I work: in your Slack and your code review, making the calls — then a clean handover. A clear end, not an open-ended arrangement.
Proof
Three turnarounds I have actually run
-
An entangled monolith became micro-frontends
I led the architectural redesign of a large, entangled frontend monolith into micro-frontends, so teams got deployment independence and the codebase stopped being one shared blast radius.
How the team and platform were built -
Pentest findings to ISO 27001 and SOC 2 in about three months
Certification ran as an engineering programme: controls, evidence collection and process changes alongside delivery, so the roadmap never stopped for the auditors.
The decisions behind it -
Platform reliability for 50+ organisations
Event-driven services on AWS with serverless autoscaling and cost tuning: more than 1,000 concurrent connections and thousands of requests a second at 99.9% uptime, on one multi-tenant platform.
The outcome in full
What you get
Four ways this starts
| Engagement | What you get | How it ends |
|---|---|---|
| Architecture and risk review | A read of the architecture, the dependency graph and the gaps an auditor will flag, with findings prioritised into now, next and later. | Written findings and a plan your team can execute without me. |
| Interim CTO / AI lead | Architecture decisions, delivery standards, roadmap and technical budget owned day to day, plus the stakeholder and board conversations. | A named successor, written decisions and a team that keeps shipping. |
| Production recovery | Quality gates, security baselines and a working path off the critical dependencies, while the team keeps delivering. | Legacy debt off the critical path and one metric that moved. |
| AI production readiness | Evaluation harnesses, human-review thresholds, observability and the security posture an AI workflow needs before it faces real users. | A workflow your team can change without breaking it. |
Bring me in while it still matters.
Thirty minutes to see whether it is a fit — I will tell you straight whether an interim CTO is what you need, or whether you would be better off hiring.
