Senior Full‑Stack SaaS Developer for Student & Counselor Web Platform (Auth + Subscriptions)

I’m the founder of a college admissions platform and already have a detailed HTML prototype of the student experience. I’m looking for a senior full‑stack SaaS developer to turn this into a production‑grade web app with secure authentication, student and counselor roles, and monthly subscriptions, as an MVP in roughly 1–3 months. The platform needs two main user types: Students: secure signup/login, dashboard, and the ability to create, edit, and save up to 20 activities per student, with all data stored safely. Counselors: secure signup/login and a dashboard to manage multiple students and view their activity data. You’ll convert my existing HTML into a real application, implement secure auth and role‑based access control, design the database schema, build the student and counselor dashboards, and integrate monthly subscription billing (Stripe or similar). I care about a modern, scalable SaaS stack (for example, Next.js + managed Postgres/auth + Stripe) but I’m open to your recommendation, including AWS if you justify it. This platform involves student data and proprietary workflows, so confidentiality and IP ownership are critical: all code and architecture you produce will be owned by me, and must not be reused or resold. Please apply only if you are senior‑level. Include: 2–4 links to similar SaaS/portal projects (multi‑role, subscriptions). Your recommended stack and a brief explanation. A short outline of how you’d structure auth, roles, database, and subscriptions. Your estimated timeline (targeting 1–3 months for MVP) and budget range. Confirmation you’re comfortable with a confidentiality/IP clause and using staging data during development.
