Eight years turning unstructured chaos into systems that think — lakehouses at 145-source scale, agents on Bedrock, and products people actually open.

Most data work dies in a dashboard nobody opens. I build the boring parts so well that the interesting parts become possible.

The Dossier

Who is doing the work, and why it tends to hold up.

Eight years ago I started as the person who fixed other people’s pipelines. Today I lead the design team on an enterprise ingestion platform pulling from 145 source systems into a three-zone lakehouse — and I still fix the pipelines, because that is where the truth lives.

The unusual part is the second half. I ship interfaces, motion and brand work with the same rigour I bring to a Spark job. Macrova, my nutrition product, went from sketch to store on both platforms. The engineering makes the creative work survive contact with reality; the creative work makes the engineering worth looking at.

§ VI

The Method

How a sentence becomes a system that runs at 3am.

  1. 01

    Idea

    It starts as a sentence, not a ticket. What should exist that does not? If I cannot say it in one line, it is not ready to build.

  2. 02

    Research

    Sources, volumes, constraints, prior art. Understand the domain before touching a keyboard — most bad architecture is a research failure wearing a technical costume.

  3. 03

    Architecture

    Zones, contracts, failure modes. Draw the system until the code becomes obvious. The diagram is the deliverable that saves the most money.

  4. 04

    Engineering

    Python, Spark, SQL, Terraform. Build it once, build it reusable, build it observable. A pipeline you cannot see inside is a pipeline you do not own.

  5. 05

    Automation

    Orchestration, CDC, audit-balance-control. If a human repeats it, it becomes a workflow. If a workflow fails silently, it becomes an alert.

  6. 06

    Deployment

    CI/CD, infrastructure as code, staged rollout. Shipping should be a routine with no adrenaline in it.

  7. 07

    Optimisation

    Cost, latency, skew, spend. The system gets faster and cheaper after it goes live — that is the part most teams never schedule.
