Full Stack Developer for SaaS Platform (Next.js / PostgreSQL)

I'm building a B2B SaaS platform for inventory management and need a full-stack developer to join the project. The core product is working with early customers — this is feature development and iteration, not greenfield. What you'll work on: - Building new features end-to-end: database through API to React UI - Real-time inventory dashboards with filtering and bulk operations - Role-based access control (admin, manager, viewer) - CSV import/export workflows with validation - Third-party API integrations (shipping carriers, accounting) Stack: Next.js 14 (App Router), TypeScript, PostgreSQL with Prisma, Tailwind CSS, deployed on AWS. Start your proposal with the word "mango" so I know you read this. Details: - $25–50/hr depending on experience - 30+ hrs/week, 3–6 months with strong potential to extend - Remote, async-friendly, but 4+ hours daily overlap with CET timezone preferred - Weekly 30-min sync + async communication in Slack/Linear You should have: - 2+ years of professional web development experience - Comfortable with TypeScript and relational databases - Experience shipping features in a production SaaS product - Good written communication (we're remote and async) Please include links to 1–2 production projects you've worked on and mention which feature from the list above you'd tackle first and how.
