Survey / Forms Platform (React, FastAPI, PostgreSQL, Redis, S3, TypeScript) overview

A survey and form-builder platform with a React drag-and-drop form designer supporting conditional logic, file uploads, and multi-page workflows. FastAPI serves the backend API for form schema storage, response collection, and real-time analytics aggregation. PostgreSQL stores form definitions and response data with JSONB columns for flexible schema evolution. Redis caches form schemas for low-latency rendering and manages response rate limiting. S3 stores uploaded file attachments. TypeScript ensures type safety across the form schema definition, rendering engine, and analytics pipeline. Targeted at SaaS companies building Typeform or Google Forms alternatives. The tradeoff is the complexity of supporting arbitrary form logic branching and the challenge of efficient analytics queries over schema-flexible response data.
