Full Stack Developer Needed for Existing SaaS App

I’m looking for a full-stack developer to help me finish a few features in an existing SaaS application. The app is already built and running. I need someone who can jump into the existing codebase, understand what’s there, and make the required changes without rewriting everything. *Stack:* Next.js, React, Node.js, TypeScript, PostgreSQL, Prisma, Tailwind For the first task, I need help with: * Adding a couple of missing API endpoints * Updating the Prisma queries/database logic * Connecting the APIs with the existing dashboard * Adding a few filters to the dashboard * Fixing some existing UI/API bugs * Making sure the changes work properly on mobile * Testing everything before delivery The requirements are already defined and I can provide the GitHub repo and details to the selected developer. I’m mainly looking for someone who is comfortable with *Next.js + Node.js + PostgreSQL/Prisma* and can work independently. Budget for this initial task is *$50 fixed price*. If everything goes well, I have more features and fixes coming up and would prefer to continue with the same developer. Please send a short proposal with: - Your experience with Next.js/Node.js * 1–2 similar projects you've worked on * When you can start
