Owned backend systems for Tutor Buddy, an AI tutoring platform used by 5,000+ students and teachers, supporting AI-driven tutoring workflows, session management, and user interactions.

Implemented an event-driven AI processing system on AWS (Lambda, SQS, SNS, DynamoDB, API Gateway) to decouple inference from request flow, preserving UI responsiveness under heavy load. Led backend design of a multi-turn AI tutoring agent with session memory using Redis (active state) and PostgreSQL (history) to provide contextual, personalized responses. Built a React/Next.js frontend with Server-Sent Events for real-time streaming AI responses, enabling multi-turn tutoring conversations. Implemented a scalable admin dashboard for multi-account management (300+ companies) processing millions of requests per da
