Product Engineer with a strong frontend background, focused on building clear, reliable and maintainable web products for complex business workflows.
I help teams turn product and operational needs into usable interfaces, prototypes and production-ready applications. My work spans the full product development cycle: understanding the problem, clarifying requirements, prototyping solutions, implementing frontend features, and contributing to lightweight backend topics when needed.
I am particularly effective in B2B, SaaS and internal-tool environments where product clarity, user experience and technical maintainability are equally important.
