Full Stack Engineer and AI expert needed

# Full-Stack Developer Needed for Growing SaaS Platform We have a B2B SaaS platform that helps small service businesses manage clients, projects, documents, and internal workflows in one place. The product is already live with a small group of users. The core functionality works, but it was built quickly during the first version and we are now moving into the next stage of the product. We are looking for a full-stack developer who can work across the existing application, build new features, and clean up parts of the codebase as we expand. This is an ongoing product, not a one-off landing page or a build from a template. **What you’ll be working on:** * Building a new client dashboard with project status, activity, and upcoming tasks * Adding role-based permissions for admins, team members, and clients * Improving our document upload and management flow * Building notifications for important project updates and deadlines * Adding filtering, search, and pagination across larger datasets * Integrating Stripe for subscriptions and account management * Improving several existing screens based on user feedback * Adding a simple AI-assisted feature that summarizes project activity for users The AI component is only one part of the project. Most of the work is standard full-stack product development. **Current stack:** * React / TypeScript * Next.js * Node.js * PostgreSQL * REST APIs * Tailwind CSS * Stripe * AWS * GitHub We are open to discussing parts of the implementation if you think there is a better technical approach. **What we’re looking for:** We need someone who is comfortable working on both frontend and backend tasks and, more importantly, can understand an existing product before making changes to it. You should be able to take a feature from requirements through implementation rather than needing every technical decision specified in advance. We’re particularly interested in developers who have experience with: * Production SaaS applications * React / Next.js and Node.js * PostgreSQL and relational data modeling * Authentication and permissions * Third-party API integrations * Stripe or similar payment systems * Deploying and debugging production applications Experience integrating LLM APIs is useful but not required. **How we work:** We’re a small team and try to keep the process straightforward. Most communication is async, with a short weekly call to discuss progress and any decisions that need input. Work is submitted through GitHub and reviewed through pull requests. We prefer small, understandable changes over large PRs that are difficult to review. There is potential for ongoing work if the first phase goes well. **When applying:** Please send 1–2 examples of full-stack products you’ve worked on and tell us specifically what you were responsible for. Also, briefly describe how you normally approach joining an existing codebase you didn’t build yourself.
