Full-Stack Developer Needed for Existing SaaS Platform

We're looking for a full-stack developer to help out with an existing SaaS platform that manages partner workflows, data pipelines, and business operations. The platform is already live and being used by clients, so this isn't a greenfield project. We have a list of features and improvements that need to be built, along with integrations and backend tasks that have piled up.   Some of the things you'll be working on: - Building new features across the full stack - Python backend + React frontend - Extending existing API endpoints and adding new ones - Adding business logic around workflows and data processing - Integrating third-party services (Stripe, Twilio, CRM, analytics) - Improving database queries and overall performance - Fixing issues as you touch related areas - Building admin dashboards and internal tools   Tech stack: Python (FastAPI/Django), Node.js (Express/NestJS), React/Next.js, PostgreSQL, REST APIs.   What we're looking for: - Strong full-stack experience - Python is our preferred backend language, but we also have Node.js services - Comfortable jumping into an existing codebase - Able to figure things out without hand-holding - Experience with SaaS products, multi-tenant platforms, marketplaces, or workflow systems If you've worked on data-heavy applications, internal business tools, or AI-powered platforms, definitely reach out. Please include examples of similar platforms you've worked on and your approach to taking over an existing codebase.
