AI Application Engineer building RAG assistants, AI agents, and vector search systems as an independent contractor.

United States

Message

As an independent contractor, I design and build LLM applications, including RAG pipelines, AI agents, and vector search systems. I developed a knowledge assistant using document chunking, pgvector, PostgreSQL, and OpenAI embeddings for grounded Q&A.

I also built multi-step agent workflows with tool and function calling, plus Redis-backed task queues for process automation. My conversational support APIs deliver structured JSON outputs through OpenAI and Claude integrations.

At Admediary, I developed web applications and backend services with React, Node.js, Python, FastAPI, and PostgreSQL. I also implemented CI/CD pipelines with GitHub Actions and Docker for AWS deployments.

Earlier, I developed PHP and WordPress solutions at Bisk and Laravel applications at Data Device Corporation and Geisinger - NIH Project. My work included REST API integrations, healthcare-related workflows, background processing, and monitoring.
