FormBoost is a production-grade serverless form submission backend API handling thousands of form submissions daily. Engineered the complete backend infrastructure during internship at Rachna Webtech as a Backend Developer. Architected PostgreSQL and MongoDB database schemas optimized for high-throughput form data storage with proper indexing and partitioning. Designed and implemented webhook delivery system ensuring real-time event propagation to customer systems with retry logic and exponential backoff. Built Node.js microservices handling email notifications, spam detection, and submission validation. Implemented REST API endpoints for form creation, submission handling, analytics, and admin dashboard operations. Integrated with email providers (SMTP) and external services via webhooks. Deployed on globally distributed infrastructure achieving 99.99% uptime.
The challenge
Building a reliable form backend at scale requires handling concurrent requests, ensuring data durability, and maintaining system reliability. Form submissions are mission-critical for customers — failures directly impact their business. Needed to learn new technologies (John Papa folder structure conventions, Node.js best practices) while meeting production standards.
The solution
Implemented database architecture separating form configurations, submissions, webhooks, and logs into optimized PostgreSQL tables with proper foreign keys and indexes. Built webhook queue system with persistent storage and retry mechanisms preventing lost events. Created microservices using Node.js and Express.js following JOHN PAPA architectural patterns for maintainability and scalability. Implemented comprehensive error handling, monitoring, and logging. Added AI-powered spam filtering to reduce noise and protect customers. Followed test-driven development practices and code review standards.
