Senior Full-Stack Developer Needed to Resolve Critical API Race Condition (React + Python)

---

---

We’re experiencing a critical race condition in our web application built with React and Python. Under concurrent API requests, the backend sometimes returns stale or conflicting data. We need a senior developer with deep experience in concurrency issues, API state management, and full-stack debugging to help us: Identify and resolve race conditions in API calls. Ensure transactional integrity in the Python backend. Implement strategies like optimistic locking or versioning. Align frontend state updates (e.g., Redux, Context) with backend logic. Tech Stack: React (TypeScript) Python (FastAPI) PostgreSQL AWS (EC2, RDS) GitHub, CI/CD Deliverables: Diagnosis and detailed explanation of the issue. Code-level fix and strategy to prevent recurrence. This task requires a developer who can dive deep into the problem, not just patch over symptoms. If you’ve resolved similar concurrency or state sync issues before, we’d love to hear how you’d approach this one.
