A list of projects with tech-stack badges tells a recruiter what you used. A case study tells them how you think. That's what gets you interviews for senior and international roles.
How recruiters read
Recruiters skim. Hiring managers read deeper. Write for both:
- Top 5 lines: the whole story in miniature
- The rest: detail for those who keep reading
The template
1. Summary (3–5 lines)
Problem: Exporters couldn't see why their farm plot data failed compliance checks. My role: Lead frontend engineer. What I built: A validation dashboard with map-based error highlighting. Result: [real, shareable outcome].
2. Context
Who the users were, what was at stake, and constraints (time, team size, legacy systems, connectivity).
3. My role
Be specific about your part versus the team's. "I designed the data flow and built the map UI; a backend colleague built the validation API."
4. Approach
Key steps and decisions. A simple diagram helps.
5. Trade-offs
The most senior-signalling section. What did you choose not to do, and why?
We chose vector tiles over loading raw GeoJSON because uploads could contain tens of thousands of plots. It added a build step but kept the map responsive on low-end laptops.
6. Results
Real numbers where you can share them. If you can't, describe qualitative outcomes honestly.
7. Lessons
What you'd do differently. This shows maturity.
8. Links
Live demo, repo, related post.
Writing about confidential work
- Anonymise clients and products.
- Generalise numbers ("thousands of plots" rather than exact counts).
- Focus on your approach, which is yours to talk about.
- Ask your employer when unsure.
