Build me a local lead research app where I can type in a query like FinTech founders in India and get back a list of real people and companies that match.

I want the app to discover candidates from public sources, enrich them with legit contact and social info when available, remove duplicates, score how relevant and trustworthy each result is, and save everything in a database. It should show live progress while the search is running, then display the results in a clean table where I can sort and review them. Please also add export options for CSV and Excel.

Make it work end to end on my machine with a browser app, an API, and a background worker so the search does not block the UI. Use Postgres and Redis locally, and include a demo mode with sample data so I can try it without any external API keys. If you need to check current docs for any libraries, look them up online first.
