Summary
Mattias Johansson is a Stockholm-based Solutions Architect and freelance data engineering consultant with over 16 years of hands-on software experience and two decades of overall engineering perspective. He specializes in generalization—replacing brittle systems with scalable data platforms (think Postgres→ClickHouse, Kafka pipelines, or serverless AWS architectures) and bringing visualizations to life with D3.js. He’s led platform builds and AI orchestration work across startups and scale-ups, from architecting global content and ingestion platforms to creating LLM orchestration and evaluation frameworks for finance. A former VP of Data/Engineering and long-time Spotify alumnus, he pairs product-savvy data thinking with frontend roots and an unusual background in theatre and video production, which he leverages to teach advanced data visualization and tell better data stories.
