Full Stack Developer Needed for Internal Automation Software

We're building an internal automation platform and need a solid full stack developer to work with us on an hourly basis. The software will handle the full data lifecycle: taking in raw data, cleaning and processing it, applying templates, generating suggestions, and storing everything in a database. On top of that we need a proper application layer around it, meaning user login, SSO integration, role based access, review workflows, and history logging so every action is traceable. What we're looking for: Strong experience building web applications end to end, frontend and backend. Comfortable with databases, API design, and authentication (SSO experience is a big plus, especially SAML or OAuth with providers like Azure AD or Google Workspace). You should be someone who can take a feature from rough requirement to working product without needing everything spelled out. We're open on tech stack, so tell us what you'd build this with and why. Python or Node on the backend with React on the frontend is the kind of setup we'd expect, but convince us if you prefer something else.
