Build My Collectible Sales Platform

I’m part-way through developing a web-based platform for selling collectible items, yet progress has stalled. The core of the job is software development: finishing the site so it is production-ready and can scale without drama. Code is already in a private Git repository and the tech stack is React, Node.js and MongoDB; you’re free to propose improvements if that will get us over the finish line faster. What still needs doing, tested and pushed live is clear: • Secure payment processing – full checkout flow, PCI-compliant handling and webhook-based confirmation. • Product search & filter – fast, faceted search that copes gracefully with thousands of SKUs and multiple categories. • Agent-managed infrastructure – automated deployment pipeline (CI/CD) plus monitoring so updates roll out with zero downtime. Once the back-end pieces are solid I’d also like help polishing the UI and producing a small set of promotional visuals that fit the “collectible sales” theme. Acceptance criteria 1. Users can register, log in and purchase without errors; Stripe test cards pass end-to-end. 2. Search returns correct results in production pipeline triggers from main branch, runs tests, and deploys on AWS with health checks green. 4. Final build ships with a concise hand-over doc: repo setup, env variables, deploy steps, and quick-start guide for the marketing graphics. If this sounds like something you can knock down quickly, let’s talk timelines and milestones so we can finally launch.
