FAQs
What remote hiring signals should I include?
Show async execution: crisp specs, discovery docs, timezone handoffs, written updates, and shipped outcomes with metrics (auth lift, conversion, chargebacks).
Does PCI work violate NDA?
No — naming frameworks (PCI DSS, 3DS) and outcomes is safe. Avoid proprietary issuer data; focus on public standards and quantified results.
How do I quantify authorization rates?
Report absolute lift (e.g., +2.4pp) and scope (region, network, MID). Add sample size and time window where possible.
Will my resume pass ATS?
Can I include portfolio links?
Yes — link to case studies, dashboards, or public write‑ups. Keep URLs human‑readable; avoid gated content.
