Apex Code Integration with Velocity Software

I need an experienced Salesforce developer with strong Apex coding skills to create a system that pulls data from the Velocity Mortgage Origination Software via its API. I have 3 objects I want to pull the data for (contact, mortgage and property). I want a button on the record pages that says something like "Get info from velocity" when that button is pressed the api is called and the relevant fields are queried from velocity. To get the loan information you can query the API by deal code which will be manually entered into salesforce, for the contact info you can query by contact name/email and the property will be related to the mortgage so can also query by deal code.

Key Requirements:
- The data to be retrieved includes Loan details, Borrower details, and Property information.
- After the data is retrieved, it needs to be saved to the Salesforce database in the corresponding record.

- Ability to create intuitive interfaces within Salesforce
