About

Practical senior engineering for teams with important work to ship.

I am a senior engineer with 20+ years of experience building, operating and improving digital products. My work spans hands-on implementation, engineering leadership, architecture and production operations.

I work best with small, capable teams that need experienced technical judgement, clear delivery habits and systems that can be trusted. The focus is pragmatic engineering: understand the constraints, make the right trade-offs and keep momentum.

Why this work matters

Useful technology needs to survive contact with the real world.

Climate, sustainability and public-benefit teams often work with difficult constraints: limited runway, changing evidence, legacy systems and high expectations from people outside the technology team. Good engineering cannot solve every problem, but it can reduce friction, make decisions clearer and give important work a stronger foundation.

My role is to bring calm senior judgement, dependable delivery and enough technical depth to help teams move forward without adding noise.

Typical engagements

Practical support shaped around the work, not a sales package.

Flexible support for founders, product leaders and small engineering teams who need steady senior input, direct implementation and better delivery habits.

01

Fractional CTO support

Steady technical judgement for founders and product leaders: architecture choices, hiring input, delivery planning and the trade-offs that shape a reliable product.

02

Platform modernisation

Incremental improvements to services, infrastructure and data flows so teams can move faster without betting everything on a rewrite.

03

MVP delivery

Hands-on product engineering for early ideas that need to reach real users, gather evidence and remain maintainable as the scope changes.

04

Technical leadership for small teams

Mentoring, code review, delivery rhythm and practical standards for teams that need senior support without adding management weight.

05

Stabilising legacy systems

Finding the operational friction, reducing incidents and making older systems understandable enough for teams to improve them with confidence.

Experience highlights

A concise view of relevant experience.

  • Engineering leadership roles across startup and scale-up environments.
  • Deep experience with AWS, distributed systems, data pipelines and production operations.
  • A delivery-focused approach shaped by two decades of building and maintaining software.
  • Climate-related, sustainability and impact work with teams that need dependable technology.
