Consulting
Work through a difficult system problem.
I work with engineering and product teams on architecture, migrations, reliability and
operating costs.
I investigate the problem, explain the options and trade-offs, and recommend a practical
next step. I can also work with your team to implement it.

Selected outcomes
Examples from building and running a platform for professional photographers (cloudspot.io), alongside the engineering team and external partners.
- Edge-compute invocations reduced by 80%. Simplified an image-delivery pipeline
by removing unnecessary caching and requests.
- Migrated data reduced by more than 50%. Audited the production database before
a large MongoDB migration, reducing the migration scope and making the cutover safer.
- Kubernetes footprint reduced by 75%. Worked with our infrastructure partner
on consolidation, alongside modernizing our delivery pipeline.
- Developer onboarding reduced from weeks to hours. Built a repeatable local
development environment, including payment events and webhooks.
Read the decisions behind the outcomes
When to bring me in
A useful starting point is one important problem that the team cannot resolve within one
part of the system.
- An older platform is slowing delivery, but a full rewrite would create more risk.
- An AI prototype needs a reliable path into production.
-
Cloud, storage, edge or inference costs are rising without a clear explanation of what is
driving them.
-
A reliability problem involves the application, data, infrastructure and cloud provider.
-
A migration or integration with an existing system is stalled, unclear or too risky to
improvise.
- Critical system knowledge is concentrated in too few people.
What the first engagement looks like
We agree on one important question, the information needed to investigate it, and the
scope and timing before work begins. I need time with the person responsible for the
decision and access to the relevant systems and evidence.
You receive a written assessment: what I found, the options and trade-offs, my
recommendation, and an ordered plan for the next steps. That gives your team something
useful whether we continue together or you take it from there.
-
Diagnose and decide
I investigate one important system problem using the relevant people, architecture,
code, production evidence and business constraints. The aim is to explain what is
happening and why.
You receive the available options, a recommendation and a prioritised action plan.
Risks, trade-offs and what remains unknown are made explicit.
-
Implement one bounded change
If the diagnostic identifies a bounded, valuable change, I can implement it with the
team. The work is tied to one agreed outcome, not the general engineering backlog.
The work includes measurement, documentation, review and handover so the team can
operate and extend the change.
-
Stay involved for high-stakes decisions
After a diagnostic or bounded implementation has established the necessary context, I
can provide ongoing, part-time senior technical support for architecture decisions,
technical roadmaps, difficult incidents, vendor choices and selected hands-on
investigation.
This does not include permanent on-call responsibility, people management or general
coding capacity.
Working fit
Good fit
- The problem has an important effect on the business or its operation.
-
The person responsible for the decision participates and the relevant information is
available.
- The team is open to incremental change and can make time for handover.
- Success can be seen in a decision made, a measured improvement or a risk removed.
Not a fit: general coding capacity, a pre-decided broad rewrite, permanent on-call
ownership or people management, or generic AI training without a system or product outcome.
Email me with what changed, what is blocked, and why it matters now. I will tell you whether
I can help and what the most useful next step would be.
