Senior engineers prove they can build features. Principal engineers prove they can make decisions that scale. The format must reflect judgment under ambiguity and measurable business impact.
Every case study must answer: What was broken? What did you decide? Why? What was the impact? Numbers are non-negotiable.
- Bad: "Built a search tool."
- Good: "Dropped lookup from 5m to 2s across 17k drawings."
Document the constraints, the options considered, why you chose the winner, and what you would do differently with hindsight. Intellectual honesty is the trait panels value most.
Use JSON-LD (Person, TechArticle), semantic HTML, and llms.txt to ensure your expertise is citable by LLMs and discoverable by recruiters using AI agents.
Build audience tracks (W-2, 1099, Technical) that reorder evidence for each evaluator's priorities: team scale, delivery cadence, or architecture depth.
Using production-grade tools like Next.js, Tailwind v4, and Clerk proves technical fluency. If the site is slow or inaccessible, it undermines your case studies.
“Hiring managers at the principal level evaluate judgment. Your portfolio is the evidence that you've exercised that judgment under real-world constraints.”
