Björn Andersson.

Passionate, driven developer with 12+ years across automotive and telecom, focused on CI/CD tooling and web applications — from on-board telematics and infotainment to large-scale continuous-integration infrastructure. Since 2020 I've run my own consultancy, Sagacity AB, and most recently turned full-time to my own products: I designed and launched refrakt.md, a framework for semantically structured Markdown that powers static sites, spec-driven planning and generative UI for AI chats — building deep, daily fluency with AI coding agents along the way.
