Knowledge Hub
Practical, opinionated reference material on the technologies enterprises actually run — written by people who operate these systems, not by people summarising vendor documentation.
Every topic opens with a Pillar Guide — one page that explains the whole subject in plain language. Around it sit tutorials, best practices, checklists, diagrams, downloads and FAQs. Start with the pillar; go sideways when you need detail.
AI
What artificial intelligence can and cannot do in a business, stated plainly — and how to tell the difference before you spend money.
Machine Learning
Models that learn from your data: when they beat simple rules, what they need to work, and how they fail.
AI Agents
Software that plans and takes actions rather than answering questions. What changes when a system can act on your behalf.
Prompt Engineering
Getting reliable output from a language model — and treating the prompt as production code rather than a text box.
RAG
Retrieval-Augmented Generation: making an AI answer from YOUR documents instead of guessing from memory.
MCP
Model Context Protocol — the emerging standard for connecting AI models to your tools and data without bespoke glue for every integration.
Enterprise Architecture
How the parts of a business fit together, and how to change one without breaking the rest.
Architecture
Designing systems that survive growth, staff turnover and requirements nobody predicted.
Software Engineering
The craft: writing code others can change safely, and shipping it without drama.
Data Engineering
Getting data from where it is created to where decisions are made — reliably, and with the numbers still correct.
DevOps
Shortening the distance between "it works on my machine" and "it works for customers".
Cloud
Renting infrastructure well: what genuinely gets cheaper, what gets more expensive, and what to keep portable.
AWS
Amazon Web Services in practice — the services worth learning first and the bills that surprise people.
Azure
Microsoft Azure in practice, especially where it meets existing Microsoft estates and identity.
Oracle
Oracle database and applications: performance, licensing and migration, without the sales framing.
Docker
Packaging an application so it runs the same everywhere. The concepts that matter and the ones you can skip.
Kubernetes
Running containers at scale — and an honest assessment of when you do not need it.
Linux
The operating layer nearly everything runs on. Practical administration, not trivia.
Cyber Security
Protecting systems and data against people actively trying to get in — including the new attack surface AI creates.
Testing
Proving software behaves before customers find out it does not.
Project Management
Delivering on time without pretending you knew everything at the start.
Business Analysis
Turning "we need a system that does X" into something a team can actually build and verify.
FinTech
Financial technology: payments, risk, compliance and the constraints that make it different from ordinary software.
