Emil Karlsson - Data Engineer and Full-Stack Developer workspace with modern development tools

Data Engineer Stockholm — n8n, Streamlit, Databricks & Data Agents

I build data chat agents and analytics that people actually use. With n8n for workflow automation, Streamlit for interactive apps, and Databricks for lakehouse workloads — I focus on usability of data, not just pipelines.

Currently shipping data agents that answer questions in plain language, replace static dashboards, and connect AI to real workflows. See my toolstack for the full stack: Databricks Genie, n8n, Qdrant, LiteLLM, OpenClaw, Mage AI, and more.
