About me

Daniel is a senior full-stack developer with over ten years of experience delivering production systems from idea to deployment. He specializes in Next.js/React, Rust (Axum, Tokio) and TypeScript/Node on PostgreSQL, with architectural ownership across the full development cycle. He has broad delivery experience from enterprise scale (Audi) to industrial real-time IoT (Mobilaris), focused on reliability, performance and clear results. Daniel is used to taking technical leadership – as tech lead, architect, Scrum Master and CTO – and works closely with teams, clients and end users. As a colleague he is self-driven, delivery-focused and collaborative. He uses AI-assisted development to shorten the path from idea to production without compromising quality. Available for remote engagements.
