I, Steven Park, added BIMI for centurion.com in 2025 and proved the customization BIMI proposal in 2026.

My Contributions:

ⓘ NOTE: Technology Leadership refused to acknowledge this achievement and went as far to say I should NOT have done it. Only my personal time was used. Business was extremely happy. CIO goals of `Best Customer Experience` and `Cyber` were the impetus. |

Customization Proposal
The centurion logo SVG was also proposed by me for BIMI in 2025.
- sourced from https://www.aexp-static.com/cdaas/one/statics/axp-static-assets/2.24.1/package/dist/img/brand/centurion-linear-gray-05.svg
However, interest dwindled given no immediate 32 KB file existed and the BIMI process requiring lawyers could take time.
Post Amex layoff I proved a 32 KB svg could be generated as part of my portfolio of work.
See SVG Tiny Portable Secure for how this 32 KB svg was achieved.
