Full-Stack SaaS Platform Development (React, Next.js, Python)

Looking for an experienced full-stack developer to help us with the next round of updates to our existing SaaS platform. The platform is already live and used for managing our internal business operations, including customer accounts, data management, and reporting. The main functionality is working well, but we have a few issues to fix and some improvements to make before moving forward with the next features. Right now, we need to update part of the dashboard, fix some validation issues in a couple of forms, and improve how data is handled between the frontend and backend. One of our existing API integrations also needs an update, as we're seeing some inconsistencies with the data it returns. Our frontend is built with React, Next.js, and TypeScript, with a Python backend and PostgreSQL database. We're looking for someone who can get into the existing codebase, understand how everything connects, and make these changes without affecting the rest of the platform. Share a couple of similar SaaS or full-stack web projects you've worked on and let us know your availability.
