Senior Full-Stack Developer - B2B Operations SaaS Platform

We are looking for an experienced full-stack developer to help us build and launch a B2B operations management SaaS platform. The goal is to create a centralized web application where businesses can manage customers, projects, tasks, team members, workflows, and reporting from one place. The frontend is built with React and Next.js, with Python and FastAPI powering the backend and PostgreSQL handling the core data. The platform also requires role-based access, dashboard views, notifications, and integrations with third-party services. We need someone who can work across the full stack, understand the existing architecture, and take ownership of features from planning through implementation and deployment. The developer should be comfortable improving existing functionality while keeping the application stable and scalable.
