Julio Calvo

I’m a Creative Developer and Digital Commerce & Marketing Operations based in Toronto, recently graduated from the Multimedia Design & Development program at Humber Polytechnic. With a background in Commerce & Marketing from Spain, I view interfaces as the intersection where business goals, design, and engineering meet.

I approach creative development with a system architecture mindset. This is best exemplified by veraOS, a productivity platform I engineered using React, TypeScript, and Supabase. From implementing O(n) drag-and-drop to end-to-end encryption and semantic search, I focused on maintainability and performance, structuring the codebase to support a production-grade experience.

I enjoy getting to the bottom of complex problems. I strive to understand the underlying logic to write code that is clear, predictable, and maintainable. I’m looking to join a collaborative team where I can contribute meaningful work on the frontend, while refining my craft through code reviews and real-world challenges.

Outside of code, I enjoy cooking, cinema, and cycling, pursuits that reward patience and consistency.
