This section documents engineering work as it happens. Entries capture architecture decisions, implementation details, operational experiences, technology evaluations, and lessons learned from building, maintaining, and evolving software systems.
About These Notes
Engineering knowledge develops through practice. Many of the most valuable lessons emerge while designing systems, investigating failures, evaluating alternatives, and maintaining software over time.
These notes provide a chronological record of that work. Some entries capture a specific technical observation. Others document architectural decisions, implementation approaches, debugging investigations, or operational experiences that may later develop into articles, presentations, or teaching material.
The emphasis is not on documenting every technology, but on recording the reasoning behind engineering decisions.
Engineering Journal
| Area | Typical Entries |
|---|---|
| Architecture | Architecture decisions, system boundaries, design alternatives, and trade-offs. |
| Implementation | Development notes, APIs, integrations, libraries, frameworks, and reusable patterns. |
| Operations | Deployment, observability, performance, reliability, security, and production experiences. |
| Artificial Intelligence | AI platform engineering, LLM applications, evaluation, RAG systems, and practical AI integration. |
| Learning | Technology evaluations, experiments, debugging sessions, and lessons learned. |
Engineering Principles
The notes in this journal follow a consistent approach.
- Record decisions together with the reasoning behind them.
- Document trade-offs rather than only successful outcomes.
- Preserve useful failures as well as successful solutions.
- Revise entries when experience or evidence improves understanding.
- Prefer practical engineering experience over fashionable trends.
- Keep the focus on systems, maintainability, and long-term usefulness.
Over time, these notes become a record of engineering practice, complementing the more structured books, articles, and reference material published elsewhere on this site.
