I am a full-stack developer specializing in AI-driven web applications, experienced in building production-ready platforms that combine modern frontend frameworks with robust backend and vector search pipelines. My projects include AI PDF intelligence, AI-assisted writing platforms, and real-time multiplayer games, each demonstrating end-to-end ownership from design to deployment.

I have engineered document ingestion, chunking, vector-based retrieval, and context-aware Q&A workflows using LLM APIs to improve relevance and accuracy for large documents, and implemented evaluation pipelines to assess content quality independent of engagement metrics. I also built realtime synchronization and game logic for multiplayer experiences using Socket.io.

I bring strong technical foundations in TypeScript, Node.js, React/Next.js, databases like PostgreSQL and MongoDB, vector stores such as Pinecone, plus DevOps practices with Docker and Git. I am motivated by building impactful AI products and collaborating on scalable, user-centered systems.
