About me
I run DJN Consulting AB, my own consulting company, and am available for new consulting engagements or employment on a remote or hybrid basis (own company, Swedish F-tax certified). My core stack is TypeScript and Rust – in the backend both TypeScript (Node.js, Bun) and Rust, and React on the frontend – with broad experience across frameworks (Next.js, NestJS, Vite SSR). I have over ten years of delivering reliable production systems from idea to operation, from enterprise scale (Audi) to industrial real-time IoT (Mobilaris). I enjoy taking technical leadership – as tech lead, architect and Scrum Master – and working closely with teams, clients and end users. As a consultant I'm self-driven, delivery-focused and collaborative, and also build my own production products (including Pratbok and Scuba). I build my own AI pipelines and agentic loops that automate repetitive engineering work – so my time goes to architecture, quality and delivery.
