00 / how I work

I do not sell advice from the sidelines.

I work between product intent and implementation. I understand the context, make the technical call, and stay close enough to the code to own the outcome.

Tell me about the work

The working loop

Understand. Decide. Deliver.

  1. 01

    Understand

    I start with the product goal, the repository and the constraints around the change. I trace the relevant data and behaviour before recommending a direction.

  2. 02

    Decide

    I reduce the problem to the smallest sound scope. Trade-offs, risks and boundaries are explained in plain language so the decision is visible.

  3. 03

    Deliver

    I deliver working code, a focused review, or recommendations your team can execute. The output matches the engagement, but it always ends with a useful next step.

How I start

A call, a repository, a Loom, production symptoms or a rough brief can be enough. I ask for the smallest amount of access and context needed to understand the problem, then I trace the relevant code and product behaviour.

How I communicate

I make scope, trade-offs and unknowns visible early. You get direct language, short feedback loops and decisions tied to the product outcome, not an abstract architecture exercise.

Engagement models

The shape follows the work.

01

Review

A senior technical review of a repository, feature, integration, or decision.

Result: Risks, decisions, and a practical next step.

02

Build

I design and implement the feature, integration, or backend change.

Result: Working, reviewed software.

03

Ongoing

Fractional senior engineering support for decisions, implementation, and code review.

Result: Senior ownership without another full-time hire.

AI in the workflow

I use AI to shorten the loop. Responsibility stays with me.

AI can accelerate

Codebase exploration, focused prototypes, test scaffolding and repetitive implementation. I use it where faster feedback improves the work.

I remain responsible for

Product trade-offs, architecture, data flow, security, failure modes, review and the decision that a change is ready to ship.

Need a senior engineer in the loop?

Start with the work in front of you. The right model becomes clear once the problem is understood.
