Consulting · Data architecture
Design every layer. Understand the whole.
Every architectural decision should be explainable and connected to a business need.
- When it makes sense
- When a growing platform makes it hard to understand its boundaries, dependencies or decisions.
- How I can help
- I design data architectures on AWS and Azure, from ingestion to analytical consumption, with explicit decisions about cost, performance and evolution.
What you receiveArchitecture map and documented design decisions.
- When it makes sense
- When you need to know who owns data, how it is protected and what requirements it must meet.
- How I can help
- I integrate cataloguing, traceability, data contracts, quality and access controls into the platform architecture.
What you receiveGovernance model and prioritised controls.
- When it makes sense
- When knowledge is scattered across code, documentation and people.
- How I can help
- I apply language models to understanding and documenting processes, keeping evidence, limitations and human review visible.
What you receiveUse-case proposal and a scoped prototype with evaluation criteria.
- When it makes sense
- When environments and deployments rely on manual work or production behaviour is hard to understand.
- How I can help
- I work with infrastructure as code, deployment automation and observability to support platform operations and evolution.
What you receiveProduction-readiness and operations plan.
Approach
From complexity to a clear platform.
A process with explicit decisions and deliverables the team can use.
Understand before proposing
I review processes, dependencies, constraints and objectives with the team to build a shared understanding.
DeliverableAssessment and initial dependency map.
Design with judgement
I define patterns, boundaries and responsibilities, with security and governance from the start.
DeliverableTarget architecture and decision records.
Turn the design into a platform
I support implementation through infrastructure as code, reproducible environments and automated deployment.
DeliverableImplementation and deployment guide for the agreed scope.
Make platform behaviour visible
I integrate observability, quality and traceability to support maintenance and evolution.
DeliverableOperations guide and improvement priorities.
