Projects

AI-Enhanced Semantic Search Service

Developed a specialized search microservice using FastAPI and pgvector to enable semantic (meaning-based) product discovery. Integrated OpenAI Embeddings to transform text queries into vector representations, improving search relevance over traditional keyword matching. Built a lightweight Next.js interface to demonstrate real-time search results with under 200ms latency.

Intelligent Error-Resolution Assistant

Architected a Django application that utilizes LangChain to analyze Python tracebacks and provide context-aware debugging suggestions. Implemented a history-tracking feature using PostgreSQL to allow users to review and search through previous technical resolutions. Designed a clean, responsive UI for code-diff visualizations using Tailwind CSS.

Real-Time Performance Monitor

Engineered a live data streaming service using Django Channels (WebSockets) to broadcast system health metrics to the frontend. Utilized Redis as a message broker and temporary data store to ensure zero-latency data synchronization across multiple clients. Visualized high-frequency data using Next.js and Chart.js, ensuring smooth 60FPS UI updates.
