Web App Criminal Background Check Code

I need a skilled programmer to build a background check code for my web application. This should be focused on retrieving criminal record information from public databases within a regional/national scope.

Requirements:
- Strong knowledge of database programming
- Proficiency in data retrieval from multiple public databases
- Prior experience building background check systems is a plus
- Understand the legality and ethics of retrieving criminal record data

Please note:
As this is focused on regional/national data, a good understanding of local public database sources is essential. No international checks are needed.
