Move batch work out of the request
Credential batches can take longer than a single web request. A queue with retries and backoff keeps issuance work separate from the interactive setup flow.

Digital credential platform
CredKit
CredKit is a credential-authoring and issuance product I am co-building. The prototype covers the path from designing a credential and preparing recipients to issuing credentials and letting a recipient check their authenticity.

(01) The problem
Issuers need to create credentials in batches and give recipients a way to verify them later.
(02) What I worked on
- 01
Visual credential studio
Built a canvas-based editor for arranging variable credential templates and previewing recipient-specific output.
- 02
Issuance workflow
Implemented recipient import, preview, issuance steps, status handling, and asynchronous jobs for batch work.
- 03
Verification mechanisms
Implemented SHA-256 hashing, Ed25519 signing, and Merkle proof helpers used by the credential verification flow.
- 04
Security review and fixes
Personally reviewed the application and made targeted remediations in the areas examined; this is not an external certification of the whole product.
(03) Engineering decisions
Give verification a concrete proof
The prototype exposes hashes, signatures, and batch proof helpers so a verifier can check a credential against the data represented by the issuance process.
(04) Delivery & status
Where it stands.
A working credential lifecycle prototype. It is not presented as a production launch or independent security certification.
- This remains a prototype; production issuance volume and customer adoption are not established.
- There is no external blockchain anchoring or formal credential-standard certification claimed.
- The implemented cryptography is not an independent audit or a blanket guarantee that the whole system is secure.
