Engineering delivery / Human–AI work design

A decision is only the beginning.

Fig. 1 A signed decision, and the road that follows it.

I lead engineering delivery in fintech, and I am building a specialisation in deciding what should stay with people when AI takes part.

When AI began drafting quality scores for customer calls, no score could count until a reviewer had checked it. Internal reporting showed evaluation time still fell by 75%.

Selected work

Three decisions, and what they changed.

All work and career
  1. Human–AI workflow

    Making AI-assisted quality review faster without removing human judgement

    The decision: AI drafts every score. Nothing counts until a reviewer has checked it.

    Financial services · Delivery coordination
    Reported · 75% less evaluation time · ≈R200k a year saved

  2. Workflow automation

    When professional verification becomes an automation problem

    The decision: Any check that failed or was uncertain went to a person; the automation never approved or rejected one.

  3. Fintech delivery

    Coordinating integrations across a multi-partner payments platform

    The decision: No partner was committed to a release until its readiness and dependencies were explicit.

One decision, start to finish

From a request to a result.

From case 01 · Reported figures

How a request for faster reviews became a design where AI does the preparation and people keep the judgement.

  1. The request

    Faster quality reviews.

    Reviewers were spending most of each evaluation transcribing and structuring a call before they could judge it.

  2. The diagnosis

    The slow part was preparation.

    And the scores fed into how individual staff were assessed, so speed could not cost explainability or a person’s right to challenge a score.

  3. The decision

    AI drafts. A reviewer decides what counts.

    AI produces the transcript and a draft of every score. A reviewer can change any score, and nothing counts until a reviewer has checked it.

  4. The result

    75% less time per evaluation

    and about R200k a year in cost saving.

Engineering Delivery Lead at Lula.

I coordinate delivery across engineering and technology support at Lula, a fintech in Cape Town: planning and prioritisation, dependencies and delivery risk, and keeping engineering and business priorities aligned.

Before that: business operations at Lula, payments and commerce delivery at Teya and Yoyo, and earlier, business analysis and Scrum roles. I write Monorati, an independent publication on the decisions behind modern work.

Let’s talk about the work.

Open to senior roles and collaboration in delivery, especially where AI is part of the work.
