Services

Senior product & engineering leadership, productised

Clear, outcome-driven engagements — from fractional CTO leadership to AI implementation and hands-on architecture. Pick the help you need now; scale it as you grow.

Fractional CTO / CPTO

Senior technical and product leadership for startups and SMEs that need direction now, not a 6-month hire. I set the technical strategy, unblock delivery and raise the bar on quality.

  • Architecture audit
  • Roadmap & priorities
  • Delivery process
  • Hiring support
  • Technical strategy

Product management & delivery

Translate ambition into a roadmap the team can ship. I run discovery, write the specs that matter, prioritise ruthlessly and keep stakeholders aligned around outcomes.

  • Product discovery
  • PRDs
  • Prioritisation
  • Sprint process
  • Stakeholder alignment

AI implementation & automation

Apply AI where it pays off — internal operations, product features and the software lifecycle itself — with measurable quality and time savings rather than hype.

  • AI workflow audit
  • Prompt systems
  • Agent prototypes
  • AI-assisted SDLC setup

Presetify services

Package your repeatable AI tasks into reusable presets and API-callable workflows your team (or your product) can rely on. See the Presetify page for the full offer.

  • Preset library
  • Workflow templates
  • Form / API integration
  • Reporting automation

Software architecture & build

Hands-on technical direction for teams that need a strong architectural backbone — backend, frontend and APIs designed to scale, with implementation support.

  • Technical specs
  • Backend / frontend architecture
  • API design
  • Implementation support

Web3 / DeFi product advisory

Navigate complex on-chain product and architecture decisions with someone who has shipped DeFi systems — smart-contract flows, tokenised logic and product/UX trade-offs.

  • Smart-contract flow design
  • Tokenised logic review
  • DeFi UX / product advisory

How it works

The same senior process, every engagement

Whether it is leadership, AI or architecture, the engagement follows the same disciplined approach.

01

Diagnose

Understand the business goal, the product, the team and the technical reality. Find the real constraint.

02

Design

Shape the roadmap, architecture and the right delivery model — and decide where AI genuinely helps.

03

Build

Execute hands-on: ship product, set up process, prototype AI workflows and raise delivery quality.

04

Scale

Harden, hire and hand over. Leave the team faster, more confident and more autonomous than I found it.

FAQ

Common questions

What does a fractional CTO engagement look like?

Typically a few days a week of senior technical and product leadership — setting strategy, unblocking delivery, supporting hiring and raising quality — scaled up or down as you need.

Do you only advise, or do you build?

Both. I work hands-on: architecture, specs, prototypes and shipping product. The mix of leadership versus build depends on what the team needs.

Which stages and company sizes do you work with?

Mostly startups and SMEs — from 0-to-1 products needing a technical co-pilot to scaling teams needing structure, architecture and AI leverage.

How do we start?

A short discovery call to understand the goal and constraints, often followed by a focused audit. From there we agree the right engagement model.
