I need a straightforward subscription system that lets users follow both residential and commercial listings and automatically emails them whenever something new matches their interests. The focus is on getting the alert workflow rock-solid: a user subscribes, chooses the property types or locations they care about, and receives a clean, well-formatted email the moment a matching listing goes live. Core requirements • Accept and manage residential and commercial listings side-by-side. • Collect subscriber preferences (property type, price range, location, etc.) and store them securely. • Generate and send real-time email alerts for new listings that fit each subscriber’s saved criteria. • Provide a simple admin screen so I can add or edit listings and review basic subscription metrics. Tech is flexible—Laravel, Django, Ruby on Rails or another modern stack is fine as long as the code is clean, documented, and deploys easily to a typical cloud host (e.g., AWS or DigitalOcean). Deliverables 1. Source code in a Git-based repo. 2. Minimal database schema with seed data for testing. 3. README with setup, environment variables, and an example alert email template. 4. Brief hand-off call or screen-share to confirm everything runs smoothly on my server.
