Durable knowledge
- High-leverage developers improve systems of work, not only typing speed.
- TDD creates a rapid behavior-feedback loop when tests describe meaningful contracts.
- SOLID highlights change pressure: focused responsibilities, substitutable implementations, small interfaces, and dependency direction.
- Version control, issue tracking, review, and automation make teamwork inspectable and repeatable.
- Service boundaries create independent evolution but add network failure, consistency, deployment, and observability costs.
- Scaling starts with measurement, statelessness where appropriate, caching, replication, load distribution, and failure planning.
Historical-value caution
Backbone/MEAN-era implementation details and old Docker/MongoDB operations are dated. The engineering principles remain useful; verify current tooling and avoid adopting distributed architecture without present-day evidence.
