What I'm looking for

I'm looking to build AI agents, RAG systems, developer tools, workflow automation, and scalable full-stack SaaS products while growing in LLM engineering.

I've built AI products including a RAG Chatbot Platform for querying custom documents, with hybrid retrieval, cross-encoder reranking, and grounded responses with citations.

My Google Workspace AI Agent uses LangGraph workflows, tool orchestration, and ReAct-style reasoning to automate Gmail, Google Calendar, and real-time search tasks through natural-language commands. I also built SmartWealth AI, a full-stack personal-finance platform with streaming agent chat, secure authentication, real-time expense management, and AI-powered spending analysis.

I'm focused on LLM engineering, workflow automation, scalable SaaS applications, and end-to-end product development with Next.js, TypeScript, Node.js, Supabase, LangChain, and LangGraph.
