Production SaaS / 2024 / Production
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. Deployed on globally distributed infrastructure achieving 99.99% uptime.
01 / 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 and conventions while meeting production standards.
02 / The solution
Implemented database architecture separating form configurations, submissions, webhooks, and logs into optimized PostgreSQL tables with proper foreign keys and indexes. Built a webhook queue system with persistent storage and retry mechanisms preventing lost events. Created Node.js/Express microservices following clean architectural patterns for maintainability, added AI-powered spam filtering, and followed test-driven development practices.
