Engineering delivery / Human–AI work design

A decision is only the beginning.

Fig. 1 The signature is the shortest part of the line.

I lead engineering delivery in fintech. Much of my work is deciding what should stay with people.

When AI began drafting quality scores for customer calls, no score could count until a reviewer had checked it. 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
    75% less evaluation time · ≈R200k a year saved

  2. Workflow automation

    When professional verification becomes an automation problem

    The decision: If a check failed or was uncertain, a person decided. Never the automation.

    AEMI · Independent engagement
    2024–2025

  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.

    Yoyo · Delivery Manager
    2022–2023
    15+ partners · 8 releases

One decision, start to finish

From a request to a result.

How “make it faster” became a design where AI does the preparation and people keep the judgement.

From case 01 · Reported figures

Stage 1 of 4

“Make quality reviews faster.”

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

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, payments and commerce delivery at Teya and Yoyo, and business analysis. I write Monorati, an independent publication on the decisions behind modern work.

Let’s talk about the work.

For senior professional opportunities and considered collaborations, especially where delivery and AI-assisted work meet.
