Ten Full‑Stack Engineering Lessons Learned from a Decade in Silicon Valley

1

CSS Specificity

Lesson: Use !important sparingly and understand CSS specificity rules (ID > class > type) to avoid breaking the cascade.

2

Designing Component State Hierarchy

Visualize UI components, map state to a hierarchy, and build matching Redux reducers to keep state management clear and avoid bugs.

3

Backend Code Organization

Adopt layered, clean architecture (separate I/O, pure data structures, dependency injection) and avoid spaghetti code by structuring code as "layered" or "screaming" architecture.

4

PostgreSQL in Production

Enable detailed logging (e.g., log_checkpoints = on, log_min_duration_statement = 1s) and use tools like pgbadger , pg_stat_statements, and auto_explain to diagnose slow queries.

5

"Haste Makes Waste"

Prioritize steady, well‑tested releases over rapid, buggy deployments; invest in code quality and comprehensive testing.

6

Invest in Automation

Implement CI/CD pipelines (e.g., CircleCI) and automated code‑review tools (Peril, Hound) to make deployments predictable and improve code‑review efficiency.

7

Master Your Tools

Learn shortcuts and advanced features of editors, terminals, Docker, database clients, and browser dev tools to boost productivity.

8

Minimum Viable Product (MVP)

Build the smallest possible product that touches all layers, avoiding unnecessary complexity while still delivering value.

9

Research‑Driven Development

Conduct user research, A/B testing, and hypothesis inversion before committing to features to ensure they solve real problems.

10

Scientific Debugging

Follow a systematic, hypothesis‑driven debugging process: reproduce, observe, state assumptions, narrow down, test, verify fixes, and iterate.
