Case studies that actually sell senior work
2026-07-01
A senior case study is not a press release. It is a decision log that helps another staff engineer answer: "Would I trust this person in my codebase?"
The failure mode
Most portfolios list logos and adjectives. They hide trade-offs, avoid stack specifics, and round numbers until they mean nothing. Cleared facts in a résumé core file are useless if the public case study still says "improved performance."
A better shape
Each study on this site aims for 800–1,500 words with:
- Situation — who had the problem and what was at stake.
- Constraints — compliance, multi-brand tenancy, multi-year support horizons.
- Decisions — why Angular vs a rewrite, why Vue for operator UIs, why static generation for browse paths.
- Outcomes — qualitative scale with method notes, not invented percentages.
Why it matters for hiring
Staff interviews probe judgment under constraints, not trivia. A case study that names a wrong stack or contradicts the résumé destroys trust faster than a gap in employment.
Write like the hiring manager can forward your study to their principal engineer — because that is exactly what happens.
