Ruoya is ready for their next project!

AI Interview Copilot is a RAG-powered interview assistant that retrieves relevant information from a personalized knowledge base and uses an LLM to generate context-aware responses to interview questions. I built the retrieval and generation pipeline to combine semantic search with prompt-based reasoning, allowing responses to stay grounded in relevant source content rather than relying only on the model’s general knowledge.

DramaClips is a full-stack short-drama discovery and affiliate platform I designed, built, and deployed end-to-end. It uses Next.js, Supabase, Cloudflare R2, Railway, and Vercel, with AI integrations for content processing and automated workflows. I also built server-side tracking and attribution to measure user engagement and conversions, turning the project into a live, revenue-generating product.

This portfolio is an interactive showcase of my work across software engineering, applied AI, 3D, and creative technology. It brings together production-ready products, technical case studies, and design projects to demonstrate how I transform complex creative challenges into practical digital experiences and connected workflows.

Home3D is an AI-assisted property reconstruction application that converts residential floor plans and listing photos into an evidence-backed, interactive 3D house. Instead of asking AI to invent an entire model, it extracts room dimensions and spatial relationships into structured scene data, validates the geometry, and procedurally generates inspectable walls, floors, rooms, and supporting property evidence.
