Durable knowledge
- A résumé is evidence of relevant outcomes, not an inventory of every tool.
- Interview stories are clearer as Situation → Task → Action → Result, with personal contribution and learning explicit.
- Before implementation, clarify users, outcomes, constraints, non-goals, dependencies, and risks.
- Estimates are forecasts under uncertainty; split work, expose assumptions, give ranges, and update from evidence.
- Meetings need a purpose, decision owner, agenda, timebox, and recorded actions.
- Clean Architecture keeps business policy independent of delivery mechanisms and infrastructure.
- Containers package runtime dependencies but do not replace configuration, security, observability, or deployment design.
- Junior professionalism means communicating early, showing evidence, asking focused questions, and closing feedback loops.
