Why the next leverage point in working with LLMs isn't larger models, it's smarter context. What "context engineering" looks like in practice, and what the discipline implies for how engineering teams build and ship.

Why the best products come from engineers who think with the product, not just for it. A practical look at the Product Engineer posture: engaging with user needs, design decisions, and continuous improvement without changing your job title.

A critique of the dominant frameworks for measuring developer productivity (DORA, McKinsey reports) and a case for measuring outcomes over outputs. Team dynamics and individual wellbeing belong in the equation as essentials, not extras.

Postgres Foreign Data Wrappers in practice: querying across databases, and even Excel spreadsheets, without a dedicated ETL pipeline or a "real" data warehouse. Cheap, surprising, and often enough.

Treating OpenAPI and AsyncAPI specs as living contracts, not just documentation. How baking spec validation into CI changes the way teams design, build, and maintain APIs in microservice-heavy stacks.

"Technical debt" has become a catch-all term for any code that needs cleanup, and the confusion drives bad project decisions. Back to the metaphor's origin: what is and isn't technical debt, why the distinction matters, and how to manage what's left.

Practical patterns for refactoring legacy code with confidence: leaning on tests, choosing the right granularity, and making each refactor small enough that "confident" is the default state, not the exception.

The heart of Trainline EU's architecture: stacks of Rack-style middlewares running on EventMachine. How treating cross-cutting concerns as composable middleware kept a complex payments and booking system tractable.

The freedom of remote work is the easy part; the hard part is the mindset shift in communication, team rituals, and organisational habits that have to change for it to actually function. Why it's still worth doing.

A walkthrough of how browsers turn HTML, CSS, and JS into pixels, with a Chrome DevTools profiling demo to make the rendering pipeline tangible. Useful for anyone debugging performance issues beyond the network waterfall.

Designing and building for a web where the device, screen size, and context are unknowable in advance. Lessons from the early responsive era on planning for change rather than for the current set of breakpoints.

A walkthrough of refactoring patterns from Martin Fowler's Refactoring, applied to real codebases. The early seed of what would become "Confident refactors" five years later at ConFoo.

An introduction to Chef as infrastructure-as-code, with a focus on continuous deployment and infrastructure testing. Early-days config management at a moment when "the cloud" still needed convincing.
