Design and ship an HTTP API: resources, validation, persistence, auth, and tests that survive refactors.
Turn a vague request into something a team can build: elicitation, testable requirements, prioritisation and the case for doing it.
Get software from your laptop to a server reliably: the shell, containers, pipelines and what to do when it breaks.
How systems get broken into and what actually prevents it — threat modelling, the common attack classes, and the controls that matter.
Move data reliably and model it so analysts can use it — pipelines that survive failure and warehouses that answer questions fast.
The problem-solving toolkit interviews test and production code depends on — and how to reason about what each choice costs.
Charts that answer a question — choosing the right form, encoding it honestly, and building a dashboard people read.
Channels, search and measurement — running campaigns judged on economics rather than impressions.
Build with language models properly: how they actually work, how to ground them in your own data, and how to tell whether it worked.
The administrative and data side of healthcare: records, interoperability, the revenue cycle and privacy obligations.
Foundations of working with tabular data in Python — load it, clean it, and find out what it actually says.
Diagnose faults methodically, understand the network underneath them, and manage a fleet of devices without touching each one.
Build, evaluate and debug supervised models — and learn to distrust a good training score.
Build apps for Android and iOS: lifecycle, declarative UI, navigation, permissions and getting through store review.
From semantic HTML to a component-driven React app, including the async model that trips everyone up.
Decide what to build and prove it mattered — discovery, strategy with real exclusions, and metrics that are not vanity.
The Python you need before anything else: data structures, functions, objects, and code that fails loudly instead of silently.
Value a property from evidence, run a transaction through due diligence, and manage client expectations through a long process.
Selling as diagnosis: qualify honestly, run discovery that earns the right to propose, and keep a pipeline that forecasts.
The defender side: detection that people trust, incident response that closes the loop, and identity as the real perimeter.
The habits that let a team change code safely: version control, tests that survive refactors, review, and designing for scale.
Query relational data with intent — joins, aggregation, window functions, and why your query is slow.
The statistics behind the models: describing data, reasoning about uncertainty, and testing claims without fooling yourself.
Research that de-risks what you build, and interaction design that people can actually use — including everyone.
