Full-Stack Developer for PaaS Website Builder -- 2

Budget: €400 fixed (Phase 1 / MVP
completion)
Stack: Next.js (frontend) + NestJS (backend)
Looking for: One serious individual full-stack developer (no agencies/teams)

Reply with the NDA (i dont accept proposals if the replies are ai generated)

I’m building a PaaS website builder (Lovable/Replit-style workflow). There is an existing codebase and I’m looking for one experienced full-stack developer to complete the remaining MVP tasks and help launch.

Scope / requirements:

The full, detailed requirements are in the attached document.
Your proposal must confirm you read it and must clearly state what you will deliver for the €400 phase, with milestones and acceptance criteria.

Phase 1 (now)
• Deliver the remaining MVP scope described in the requirements document
• Work in my existing codebase (Next.js + NestJS)
• Provide basic documentation and clean handover

Maintenance + next phases (after launch / after revenue)

I want long-term collaboration. I need maintenance right after launch (bug fixes + stability), but I’m bootstrapping. The plan is:
• A limited post-launch stabilization period, then
• Ongoing maintenance + new phases become paid once revenue starts (hourly or retainer after we hit an agreed revenue milestone)

Who I want:
• Individual developer only (no corporates/agencies)
• Proven Next.js + NestJS experience
• Experience shipping SaaS products with payments/webhooks, admin tooling, and non-trivial backend features
• Clear communication and comfortable working with milestones

How to apply (screening):

Start your proposal with: “Next+Nest”
Then include:
1. 2–3 relevant projects you personally built (links/screenshots + what you implemented)
2. A short technical summary of how you would handle the hard parts in my requirements doc (preview/export/payments/admin, etc.)
3. A milestone plan for the €400 phase (deliverables + acceptance criteria)
4. Your availability and expected delivery for the agreed scope

NDA:

I’m attaching an NDA/IP agreement. Only sign after you are 100% sure you want and can do this. We will sign before any sensitive access (keys/production).
