Summary
👤
Senior🎓
Top SchoolDenis Gridchin is a software engineer and design-systems architect based in Barcelona with over a decade of experience building high-performance, user-centred frontends for large-scale educational and consumer platforms. He has driven measurable impact—co-authoring and evolving the TES Design System, tripling load speed on the site’s busiest pages and cutting client bundle size by 85% through careful refactoring. Comfortable bridging design and engineering, Denis has led frontend teams, mentored juniors, and defined design-system strategies that span multiple products and platforms. His background combines formal design education with deep practical expertise in responsive, accessible web interfaces and performance optimisation. Currently at Infinitas Learning, he focuses on transforming learning experiences through scalable, maintainable frontend architectures. An often-overlooked strength is his track record of organizing hands-on engineering rituals (like TES Frontend Days) that reduce tech debt while accelerating product delivery.
