WORK WITH AYAN

Technology & AI Advisory

Independent technology and AI judgement for founders, leadership teams, boards and investors. Start from the situation you are in; the right form of support usually follows from it.

Discuss a requirement

Need senior technology leadership?

Fractional CTO

Embedded technology and AI leadership for organisations that need ongoing executive ownership without a full-time CTO appointment.

Virtual CTO

On-demand strategic technology advice and decision support, without day-to-day executive management.

Need to understand your AI position?

AI Readiness Assessment

Assess strategy, data, architecture, people, governance and operational capability before scaling AI.

AI Strategy Advisory

Prioritise AI opportunities and build a realistic implementation roadmap.

Need confidence in your architecture?

Technology Architecture Review

Independent assessment of architecture, scalability, technical debt and future readiness.

AI Architecture Review

Review RAG, LLMs, agents, security, observability, governance and AI platform architecture.

Making an investment or major technology decision?

Technical Due Diligence

Independent technology and AI diligence for founders, investors, acquirers and boards.

Need leadership alignment?

Executive AI Workshops

Practical workshops for leadership and engineering teams.

HOW I WORK

Judgement, independent of delivery

Decisions before deliverables

Every engagement is organised around the decisions you need to make: what to build, what to change, what not to build, and how to govern the risk.

Independent of delivery

Advice is not shaped by who implements it. If Webskitters is the right delivery partner I will say so plainly; if it is not, I will say that too.

Evidence over assertion

Findings are tied to what was reviewed: architecture, code, data, process and people. Where something cannot be verified, the report says so.

GETTING STARTED

How engagements begin

01 →

Share the context

Use the form on the relevant service page, or the contact page if you are unsure which fits.

02 →

A focused first conversation

We discuss the decision, the constraints and whether I am the right person to help.

03

A written proposal

Scope, format, involvement and outputs are agreed in writing before any work starts.

NOT SURE WHICH FITS?

Describe the situation.
We can work out the rest.

Most engagements start with a question rather than a service name. Share the context and I will suggest the most useful form of support, including when that is not me.
