Architecture decisions for software and platform systems.

Notes for tech leads and senior fullstack engineers working across application and platform concerns. I write about performance, observability, deployment topology, operability, and the trade-offs behind design and delivery decisions.

Some articles are software-heavy, others are platform-heavy. The common thread is production constraints, clear assumptions, and what breaks first.

Flux Delivery

Start with the delivery model: control plane, data plane, ownership boundaries, and promotion flow.

Promotion Decisions

Follow the decision path: Git vs OCI, floating tags, and the trade-offs behind promotion models.

Operations & Observability

Go deeper into incident visibility, correlation, and production metadata around Flux delivery.
