> Selected work demonstrating this service.

- [Presented 200 UI/UX improvements for the GIS map application, boosting revenue by 10x through enhanced software features.](https://advisory.engineer.company/portfolio/presented-200-ui-ux-improvements-for-the-gis-28/)
- [Designed the product's UI and UX end to end — directory grids, dual card/table views, live requirement validators and breadcrumb navigation.](https://advisory.engineer.company/portfolio/designed-the-product-s-ui-and-ux-end-76/)
- [Established PDF/UA‑1 conformance across nine documents at 106 of 106 rules, and found the archival variant failing one rule of 146 — a near‑miss that reads as a pass to anyone not running the validator.](https://advisory.engineer.company/portfolio/established-pdf-ua-1-conformance-across-nine-documents-146/)
- [Rewrote the application's error messages against a written tone standard after a refused sign‑in blamed the user for mistyping when the provider actually required an app‑specific password, and covered it with a test that names the provider.](https://advisory.engineer.company/portfolio/rewrote-the-error-messages-against-a-tone-standard-162/)
