Peter K.

Senior AI Engineer & Solution Architect | RAG, Agents & GIS

I architect, build, and lead the delivery of AI and geospatial platforms. My experience spans 15+ years of software development and international technical projects, including systems for the United Nations and GIS work at TomTom. My recent work includes platform architecture and cloud migration for THRIVE360, alongside a LangChain-based AI assistant for a vaccination monitoring platform covering 64 countries. I implemented tool calling against operational APIs and RAG over technical documentation, using Chroma before migrating retrieval to Databricks AI Search. I also co-led a document-processing platform using Azure Document Intelligence and developed classification models with PyTorch, BERT, and Transformers. My geospatial background combines an MSc in Spatial Planning and GIS with experience in mapping, spatial analysis, and satellite imagery classification. I take responsibility across architecture, backend development, data integration, debugging, and deployment. I work with Python, Node.js, React, PostgreSQL, Azure, AWS, and Databricks, with LangSmith for tracing agent execution. I’m interested in senior engineering and technical ownership roles involving AI agents, RAG systems, and geospatial applications—from designing the architecture to resolving production issues and leading continued development.
