technical skills · architecture

An interconnected stack

Four infrastructure layers — each component is a tool I reach for to ship production systems.

layer · 01

Programming

Languages and runtimes I write production code in.

layer · 02

Data Engineering

Building pipelines, orchestrating jobs, modelling state.

layer · 03

Cloud & DevOps

Shipping containers, infrastructure, and CI/CD.

layer · 04

AI & ML

Modelling, agents, and the visualisation layer on top.

projects · deployable services

Shipped systems, not slides

Each project is a deployable service in the infrastructure grid — architecture, stack, and source code.
