How we work together

I usually get involved when…

  1. 01

    Engineering isn't delivering.

    Deadlines keep moving, quality is suffering or nobody can clearly explain why progress is so difficult.

  2. 02

    You don't know whether to trust the technical advice you're getting.

    Your internal team, agency or vendor has an answer — but you cannot independently tell whether it is the right one.

  3. 03

    A big technology decision is approaching.

    Build or buy. Rewrite or improve. Migrate or stay. Invest, change direction or stop.

  4. 04

    The product is growing faster than the technology around it.

    Reliability, scalability, cloud cost, technical debt or operating complexity are becoming business problems.

  5. 05

    You have something worth building, but not yet the technical organisation to build it.

    A new venture, product idea, prototype or AI-built tool now needs realistic scope, architecture, team, cost and execution.

  6. 06

    You need experienced technology leadership, but not necessarily another permanent executive.

    A CTO has left, leadership is missing, an existing technology leader needs reinforcement, or an important initiative needs senior ownership.

Need clarity? / CTO Review

You probably need a CTO Review if…

  • Your developers keep missing deadlines and you no longer know whether the estimates are reasonable.
  • Your agency or engineering team says everything is complicated, but you cannot independently tell whether that is true.
  • Someone is proposing a rewrite, migration or major rebuild and you are about to commit serious money to it.
  • Engineering costs keep growing, but it is not obvious what the business is getting for the money.
  • The product works today, but you are worried the technology will not survive the next stage of growth.
  • Your CTO or technical lead has left and you need to understand what state the technology and team are actually in.
  • You have a product, prototype or AI-built tool and need to know what it will really take to turn it into a reliable business.
  • You are being asked to approve a major technical investment and want an independent opinion before saying yes.
Outcome

An independent view of what is actually happening, the important risks and decisions surfaced, clear recommendations, and a prioritised plan for what happens next.

The investigation adapts to the actual problem across technology, delivery, people, architecture, cost, risk and business context. It is not a generic checklist audit.

A review may lead to Fractional CTO work, but it does not have to.

Need ownership? / Fractional CTO

Senior technical ownership, at the level the business needs.

  • You need an experienced technology leader, but a permanent executive hire is not the right move yet.
  • A CTO or technical lead has left and the business needs clear senior ownership while it decides what comes next.
  • An existing technology leader or engineering team needs experienced reinforcement to move an important initiative forward.
  • Technology decisions, delivery risk or architecture are becoming business-critical and need someone accountable for the outcome.
  • The product is growing and the connection between business priorities and engineering execution needs stronger leadership.
  • Vendors, partners or a distributed team need senior technical direction and a clear point of ownership.
Outcome

Clear senior technical ownership, stronger execution and sustained progress without immediately committing to a permanent CTO hire.

I step into your business and connect its priorities with execution. The engagement is defined by leadership, responsibility and outcomes — not a monthly allocation of consulting hours.

01

From MVP to a global production platform

Scaled without starting over

A product evolved through multiple business stages into a mature global platform by adapting its technology rather than repeatedly discarding it.

02

From founder-led engineering to a technology organisation that could run without the CTO

Built sustainable technology leadership

Engineering capability matured across people, ownership and operating practices until day-to-day leadership no longer depended on one person.

03

A prototype that changed the direction of the company

Turned technical experimentation into business direction

A prototype made an uncertain idea concrete enough to learn from and helped executives make a consequential change in direction.

04

Changing a business-critical platform without breaking anything

De-risked a major live change

A global partner integration changed through compatibility, staged rollout and reversibility while existing publisher behaviour kept working.

05

Reliability has a price. So does overengineering.

Matched reliability to business value

Infrastructure cost, graceful degradation and recovery were balanced against the real business impact of a temporary failure.

06

A decade-old platform didn't need a rewrite

Avoided unnecessary reinvestment

A mature platform improved incrementally while valuable compatibility and accumulated operating knowledge were preserved.

Portrait to be added

Artur Wiśniewski

Fractional CTO / Technology Leader

For more than a decade, I’ve led technology across people, product and engineering — helping complex products evolve through pivots, growth and years of production use. I operate as a technology leader while staying close enough to the work to challenge assumptions and collaborate directly with engineers.

I make complicated technology understandable to non-technical decision-makers. My approach is commercially pragmatic: clarify the trade-offs, make the decision the business needs and account for its long-term consequences.

01

Technology leadershipMore than a decade operating as a CTO.

02

People, product and technologyLeadership across teams, delivery and architecture.

03

Clear communicationTechnical complexity translated into useful business decisions.

04

Commercial judgementReliability, risk and cost matched to business value.

Let’s bring clarity to your technology decisions.

A short conversation can save months of uncertainty.
