A compact, shareable artifact of one skill. Something a hiring manager can open in thirty seconds — instead of taking “expert in SQL” on faith.
“Expert in SQL. Optimized slow reports.”
Nightly ops report, 14 min → 11 seconds. Added a covering index on (account_id, created_at), rewrote the scan as a range seek, attached EXPLAIN before/after. One page. One skill. Link or PDF.
Not a portfolio dump. The thing they keep asking you to prove.
Send it. They open it. Host it wherever you want, or attach it.
Hiring managers do not read. Evidence first, adjectives never.
Swap the proof, keep the frame, next job or next client.
No. It sits next to a resume — or replaces one claim on it — with a compact proof of a single skill.
You get the file. Host it, attach it, or print it.
