Real-Time Quiz & Examination Platform
- ✦Scaled live examination sessions to 5,000+ concurrent users by implementing WebSocket fan-out through Ably Pub/Sub, with connection-drop recovery and automatic session reconnection.
- ✦Engineered a sub-100ms leaderboard system using Redis Sorted Sets (ZRANGEBYSCORE) synced with PostgreSQL on AWS RDS, maintaining rank accuracy under sustained concurrent write pressure.
- ✦Designed time-based bonus and linear-retardation scoring algorithms to rank participants by response speed and precision, preventing score-gaming edge cases in competitive quiz formats.
- ✦Containerized backend microservices with Docker and deployed on AWS infrastructure, handling peak traffic spikes during live examination windows without degradation.
AI-Powered Adaptive Learning Platform
- ✦Architected and launched an end-to-end AI-powered learning platform from 0→1, integrating Spring Boot with Spring AI for LLM orchestration and content generation pipelines.
- ✦Built an interactive real-time AI technical interview simulator using OpenAI Realtime SDK, supporting streamed conversational exchanges with context-aware follow-up questioning.
- ✦Implemented vector embeddings and semantic search retrieval pipelines to enhance learning personalization, matching user queries to relevant course material with cosine similarity ranking.
- ✦Reduced LLM inference costs by 40% through prompt structure optimization, context window management, and API response caching across repeated learning sessions.
