Full-Stack SaaS Build & Integrations

I’m kicking off a two-month sprint to turn a system-design ontology into a working SaaS platform. Here’s the scope I need you to cover from end to end:

Backend
• Spin up a Node.js / Neo4j backend that ingests and applies my existing ontology to drive business logic and data relationships.
• Expose clean REST or GraphQL endpoints, complete with unit tests and concise API docs (Swagger or similar).
• Set up a lightweight CI/CD pipeline so every merge automatically deploys to a staging environment.

Third-party connections
• The immediate priority is integrating “Tools” APIs—think version-control, project-management, or other productivity services our customers already use. If the roadmap later calls for Payment gateways, Social media APIs, or Analytics services, the codebase should be modular enough to add them with minimal refactor.

Frontend & UX
• We’ll decide together between React, Vue.js, or Angular once we map user flows, but I expect a responsive, polished UI that mirrors the ontology’s structure and surfaces real-time data from the backend.
• Deliver reusable components, state management, and a style guide so future screens stay consistent. Figma or a similar prototyping tool for quick sign-off is a plus.

Deliverables
1. Detailed technical plan and timeline.
2. Functional prototype for early feedback.
3. Production-ready frontend and backend, fully integrated.
4. Deployment scripts and hand-over documentation.

I’m ready to start as soon as we align on the tech decisions; timeline is 1–2 months max. If you have solid full-stack chops, proven API integration experience, and an eye for clean UX, let’s talk.
