At Upwork, I integrated OpenAI, Gemini, and Ollama models into SaaS products and enterprise systems, and built automation pipelines with n8n and Python. I completed 80+ projects and logged over 3,900 billable hours.
I designed and deployed a real estate document-processing and lead-handling workflow using local Ollama models, n8n, and self-hosted Linux infrastructure, reducing processing latency by 60%. I also architected an enterprise RAG system with ChromaDB and FastAPI, delivering answers with under 1.2 seconds average latency.
