What I'm looking for

I’m looking to build production-ready Generative AI—RAG and autonomous agents—with scalable FastAPI backends, optimizing LLM workflows and real-time retrieval so engineering teams ship reliable AI features faster.

I’m a performance-driven AI Engineer with a strong Computer Science foundation and published research in Deep Learning. I specialize in building scalable Generative AI applications, with a focus on RAG architectures and LLM workflow optimization.

In my projects, I engineered a PDF Chatbot using Retrieval-Augmented Generation, enabling semantic search across documents with high contextual accuracy. I also developed LLM-powered customer support and automation systems across multi-platform messaging (Messenger, WhatsApp, Telegram, Instagram) using n8n.

I further built an autonomous AI Agent with LangGraph and LangChain, including multi-step reasoning and real-time web research through Tavily. I am motivated by turning AI ideas into production-ready, maintainable experiences.
