Salesforce Developer for KYC Plugin & AppExchange Publishing

We need a Salesforce developer to build a managed package plugin for integrating a KYC (Know Your Customer) platform into Salesforce and assist with publishing it on AppExchange. The plugin enables KYC checks on Contact or Lead records, with status updates via a middleware server (details will be provided).

Tasks
- Develop a managed package with custom fields (e.g., KYC Status) and Apex classes.
- Create Lightning Web Components for:
- Initiating KYC checks from record pages (e.g., a button).
- Displaying KYC status/results.
- Configure Named Credentials for middleware authentication (OAuth 2.0).
- Implement REST API calls for KYC requests and webhook updates.
- Support refresh tokens for session management.
- Write unit tests (80%+ coverage) and ensure security (no hardcoded credentials).
- Provide a setup guide for installation and configuration.
- AppExchange Publishing:
- Prepare the package for AppExchange submission (e.g., security review compliance, metadata optimization).
- Assist with creating AppExchange listing content (description, screenshots, logo).
- Support the security review process, including documentation and addressing feedback.

Deliverables
- Managed package ready for AppExchange submission.
- Sample Lightning page for demo.
- Setup guide (installation, Named Credentials config).
- AppExchange listing materials (description, images).
- Clean, tested code with 80%+ test coverage.
