Builder

Vitalii Znak

Senior full-stack engineer | Applied AI & data · Zurich, Switzerland

I build software end to end, from data and APIs to interfaces. 10+ years across energy, finance and real-time products, working with TypeScript, React, Python and Node.js. I've shipped a RAG/LLM app and worked on solar monitoring and building simulations. Curious about science, maths and engineering. I enjoy turning complex problems into useful tools and building with people who care about getting things right.
