Johan Grandas

AI Engineer & Frontend Developer

I build polished, accessible, AI-ready digital products across frontend, backend, databases, mobile, and production integrations.

About me

I am an AI Engineer and product-minded developer focused on building accessible, responsive, and well-structured digital experiences for real-world products.

Since February 2026, my work at Exus has expanded into AI engineering across frontend, backend, databases, mobile workflows, automations, integrations, and end-to-end product delivery.

Before that transition, I worked as a Senior Frontend Developer across client websites and internal platforms, including LiveConnect, where I contributed to accessibility-focused interface improvements, theming systems, language options, and flexible typography settings.

I enjoy turning complex ideas into clear interfaces, reliable systems, and production-ready product experiences that feel simple for the people using them.
