What I'm looking for

I'm looking to build end-to-end production AI systems, including LLM platforms, enterprise RAG, agentic workflows, and reliable self-hosted inference infrastructure, in a remote role.

I've built production AI systems at INITI, including an internal OpenAI-compatible platform, enterprise RAG retrieval for corporate knowledge, an AI testing agent, and an analytics dashboard copilot. I deploy self-hosted LLM workloads with Python, FastAPI, vLLM, and NVIDIA Triton Inference Server.

Across Intelligent Systems, ESN, Healbe, and Zolle, I've delivered computer vision, NLP, ML deployment, cloud data warehouse, ETL, analytics, and reporting systems. I also teach LLM engineering and AI-native architecture, drawing on 15+ years in technology and digital products.
