Petro411 is a full-stack SaaS platform I built for a U.S.-based client, giving landmen and oil & gas professionals fast, verified access to mineral owner contact data, phone numbers, emails, and addresses searchable by county and state across the U.S. I developed the entire product using Next.js for a fast, SEO-friendly frontend, MongoDB for scalable data storage of county-wise mineral ownership records, Axios and React Query for efficient API communication and caching, and Stripe for subscription billing and tiered access control. The platform supports free limited search, paid county-level data downloads, multi-county bulk exports, and a secure member dashboard — solving a real data-access problem for the U.S. land and mineral rights industry.
