I’m building a tailor-made content management web application and need a full-stack developer who is completely comfortable with Next.js on the server and client, Fabric.js for rich in-browser editing, and Stripe for handling payments and subscriptions. The core of the product is a CMS, so everything revolves around fast, secure content workflows: • User authentication that supports sign-up, login, role management and token-based sessions. • An intuitive, WYSIWYG-style editing experience powered by Fabric.js, letting non-technical users drag, drop and tweak content with zero code. • A multi-step content approval workflow so editors can submit, reviewers can approve or request changes, and only final items go live. Stripe will tie in for plan management and metered billing; please factor in webhooks, retries and a clean customer portal. I’d like to see a detailed project proposal explaining your architecture choices, timeline, and how you’ll break milestones down. Reference past projects briefly if they help illustrate similar challenges you’ve solved, but keep the focus on how you’ll execute this build. Code must be clean, well-documented and pushed to a private Git repository that I’ll provide. A staging deployment on Vercel (or similar) is the go-live target for the first milestone, followed by production hardening and final hand-off.
