One person, the whole stack: the system design, the services underneath, the cloud it runs on, and the screen someone actually touches. Eight years of it — data pipelines in the UK, backend services in Japan and Ireland, platform work at AWS.
Most products get handed across five specialists and lose something at every seam. These are the layers I carry myself — from the first diagram to the thing that renders.
RAG, agent orchestration, evals and fine-tuning. The hard part was never the first prompt working — it is the hundredth.
The diagram before the code — boundaries, failure modes, what breaks at ten times the load. Most production pain is a week-one decision.
APIs built to be boring: high throughput, sub-millisecond, and still standing the morning after traffic triples.
AWS and GCP as code — Kubernetes, Terraform, CI/CD and observability you can actually debug at three in the morning.
React and TypeScript wired straight through to Python and Go. The half of the product people actually judge you on.
Kafka, Spark, dbt and Airflow — the plumbing that decides whether your model ever sees the truth.
Data first, then the services, then the cloud under them, then the models on top. Nobody handed me the stack — I picked it up a layer at a time. Pick a stop.
Pipelines, ETL and warehousing on Hadoop and Spark — turning raw feeds into something a business could actually decide on. Lived in the UK and travelled Europe between deploys.
Services and APIs across global teams: Japan first, then a relocation to Ireland and platform work at AWS. Robust beats clever when five teams depend on your endpoint.
Architecture and platform work for clients — and increasingly, dragging LLM systems out of the demo and into something that gets paged at 3am. The layers finally became one job.
One from each layer — the infrastructure, the agents, the services, and the analysis tooling I actually run for myself. All of it public.
AI product builds, senior engineering roles, and consulting where the whole stack is the job.
