Ihar Ivaniuk — Senior Frontend / Full-Stack Engineer. I build products where engineering, AI and automation meet. End-to-end ownership — from discovery and architecture to CI/CD and production reliability. React / Next.js, Node.js, content platforms, and data-heavy systems, including live-stack modernization. Technical consulting and mentoring when a team needs leverage, not another full-time hire.
