Senior Full-Stack Developer – Review, Polish & Launch AI Real Estate Lead Platform

Description: I’m a non-technical founder building SoCalForeclosures.net — a subscription platform for Southern California real estate investors. Lead Members pay $149.99/month (capped at 8,000) to access scored off-market foreclosure and pre-foreclosure leads. Members work leads in a built-in CRM and sell deals through an internal marketplace to cash buyers (free tier or $99.99/month First Look). A working prototype is already built and deployed. Core features including user authentication, PayPal payments, marketplace (SoCalDeals), MyCRM pipeline, Phantom lead scoring engine, admin tools, and bot management screens are functional with demo data on a professional dark theme. Current honest status: The automated “bot army” that will pull real public distress signals from county recorders, courts, tax collectors, legal newspapers, trustees, and paid data sources is scaffolded but not yet actively ingesting live leads. A detailed signal catalog and county data sources are already documented. Project Scope (Fixed Price): I need an experienced senior full-stack developer to take the existing prototype and deliver a fully functioning, production-ready platform that is live and online. This is a single fixed-price engagement. Key deliverables for this project: Full code review and audit of the current Next.js + Express + PostgreSQL + Prisma codebase Polish and improve visual design and user experience across the member dashboard, lead feed, CRM, and marketplace so it looks professional for serious real estate investors Activate and productionize the real data pipeline (bot army) so it can ingest actual leads from public and paid sources according to the existing signal catalog Fix bugs, performance issues, technical debt, and operational problems Migrate hosting from the current European server to a reliable US-based provider with proper deployment pipeline, monitoring, and backups Stabilize the site so it runs reliably in production Deliver clear documentation and handover Important notes: This is not a from-scratch build. A substantial amount of the website and backend already exists and is deployed. The goal of this fixed-price project is to complete the remaining work and launch a fully functioning, live platform with real data capabilities. Once the website is successfully deployed live and online, we will negotiate a separate ongoing contract for maintenance, upgrades, new features, and additional work (including potential iOS and Android mobile apps). Tech stack: Next.js 14 (App Router) + TypeScript + Tailwind Express backend + PostgreSQL + Prisma Existing TypeScript bot framework (Playwright / Cheerio) PayPal payments, Twilio, Resend, Mapbox Ideal candidate: Senior full-stack developer with strong experience in TypeScript, Next.js, Prisma/PostgreSQL, and data pipelines or web scraping (public/government data sources) Experience taking prototypes to production, including hosting migrations and operational stability Comfortable working with an existing codebase and delivering clear recommendations to a non-technical founder Proactive, reliable, and quality-focused Project type: Fixed Price (one set price for the full scope above to get the platform fully live and functioning). To apply, please: Propose your fixed price for completing this project (review + polish + activate data pipeline + hosting migration + full production launch). Share 1–2 examples of similar past work (taking existing code to production, data platforms, or marketplaces). Briefly describe how you would approach reviewing and completing an existing prototype. Confirm your experience with US hosting providers and data pipeline / scraping work. Any questions about the current state or scope. Serious applicants will receive the full technical documents (Developer Brief, Signal Catalog, and County Data Sources) under NDA. Project owner is based in Southern California.
