About

Alejandro Grajales · Frontend Developer

From design to product development.

Since September 2025 I've been a Mid-Level Frontend Developer at Linktic, where I work with Vue; in my own projects I also use React, Next.js and TypeScript. I studied software development, and before that I spent 15+ years as a graphic and web designer. That background lets me turn a Figma design into a precise, consistent interface and suggest user experience improvements.

Beyond the interface, I build complete products: databases and authentication with Supabase, integrations with external APIs, bots and AI-powered workflows. I also hold a degree in music, and mixing music with code led to a plugin for OBS.
