A company outgrows the point where technology decisions can be made in passing long before a full-time CTO is easy to justify. A fractional CTO closes that gap: architecture, vendor selection and technical sign-off for a few days a month instead of a permanent hire. Over 15 years in fintech, blockchain and cybersecurity I have run that arrangement across six countries, and I start every engagement the same way: with a short audit before anything gets rebuilt.

When a fractional CTO fits and when you need a full-time hire
You need a full-time CTO when technology is the product, development runs every day and decisions have to be made within the hour. Then what you need is a job profile, not me: when releases go out daily, a few days a month decide nothing.
The fractional arrangement fits a different case: development sits with a contractor or a small team, the decisions are large but infrequent, and the cost of a mistake is high precisely because nobody is there to check. What the founder lacks is not hands but a second opinion from someone who reads what the contractor sends and sees what does not belong there.
What the work covers
- Architectural decisions, and revisiting them when the product changes.
- Selecting contractors and signing off technically on what they deliver.
- The technical section for investors, and answering their experts’ questions.
- Interviewing developers and building processes inside the team.
- Post-incident reviews and deciding what to change so it does not recur.
Architecture and infrastructure
Most architectural trouble comes not from picking the wrong technology but from designing for load that does not exist yet and paying for it immediately. The opposite mistake is rarer and dearer: the system was built on one server and the growth was needed yesterday.
The work starts from what load is realistic over the coming year and what a rebuild would cost if that forecast turns out wrong. Operations are treated separately: who finds out that something broke, whose name the provider accounts are in, and what happens if the contractor stops answering. From practice: Monolith Plus, a secured infrastructure platform for mid-sized business. After its architecture was rebuilt, latency fell by 67% and load grew from 10,000 to over 100,000 operations a day at 99.9% availability. On the MStar platform, moving to microservices sped up releases: for a founder, a predictable time from fix to production beats a tidy diagram. What that looks like across a large estate is described in Infrastructure fleet management.
Fintech, blockchain and security
In fintech, technical decisions hit regulation before they hit load: where data is stored, who can reach it, how a customer’s identity is confirmed, and what happens when a regulator asks. An architecture without answers to them has to be rebuilt whole.
From practice: the blockchain education platform CryptoMBA, where I was CTO. Until the project was deliberately closed in January 2025 it served more than 50,000 users in 38 countries. A separate area is crypto-asset custody and smart contract review, where a mistake cannot be rolled back with a patch.
What decides things in this seat is not the tools you buy but the dull parts: separated access, named accounts instead of one shared production password, and logs somebody actually reads. A product bought to sit on top of a leaky design adds an invoice, not protection.
I do not deploy a SIEM myself, write policy for a certification or run penetration tests. The perimeter and the regulations belong to information security; my part stops at who has access to what.
Team and hiring
A founder without a technical background can barely assess a developer in an interview: the strong and the weak both speak convincingly. A single bad hire in a small team costs months, which makes the technical part of interviewing the fastest thing to pay for itself.
After that come processes the team can actually keep to: code review, test environments, a release procedure. Sized to the team rather than copied from a textbook. A process written for thirty people will not be followed by three.
Technical due diligence
When an investor sends in their own experts, someone on the company’s side gives them access, explains the decisions that were taken and turns their findings into a work plan: in the monthly arrangement that part is mine. The review as a project of its own, and preparing for one, is investor readiness and due diligence.

What I do not do
- I do not build the product myself and do not replace a development team.
- I do not take arrangements where only a name on an investor deck is wanted.
- I do not bring in a development team of my own and take no percentage of the contractor’s fee: sign-off is worth nothing if I do.
- I do not carry more than a few companies at once: the format loses its point without time to go deep.
How the engagement runs
A monthly arrangement at $6,000 (AED 22,000) per month: a fixed number of days, a standing meeting with the founder, and availability for urgent decisions in between. The first month almost always goes on understanding what is already built; without that, a recommendation would be about a generic company.
- Month 1. A review of what exists: code, infrastructure, contractor agreements, risks ordered by what they cost.
- Month 2. Architectural decisions in priority order, and a sign-off procedure for what the contractor delivers.
- From then on. The rhythm: the meeting, sign-off, incident reviews, and revisiting decisions as the product changes.
The agreement is monthly with no minimum term. If the first review shows you need two weeks of work on a sign-off procedure rather than a standing arrangement, that is where it ends.

Frequently Asked Questions
How much time do you give a company?
Usually a few days a month, with a standing meeting and availability in between. The exact number is set after the first review: before that, any figure would be guesswork.
How is this different from consulting?
A consultant answers the question asked and leaves. A fractional director owns the outcome of decisions over time: if the architecture I signed off does not hold six months later, dealing with that is my job.
Do you work with companies outside the UAE?
Yes. Projects have been delivered in six countries and the work is mostly remote. For the UAE and the GCC, meeting in person is possible.
What happens when I no longer need you?
The normal end of the arrangement is that you hire a full-time director and I hand over to them. By that point the decisions and the reasons behind them are documented, so the handover takes weeks rather than months.
