Hey, I'm 👋 Johnny. Currently a Full Stack Developer @ AgileAlgo, an AI-focused company crafting intuitive, polished digital experiences with a focus on detail and user-centered design.

Interested in front-end development with React and Next.js, working with REST APIs, and managing content using Strapi CMS. Comfortable contributing to full-stack work when needed, including backend tasks with Express and MySQL.

Psst…! Beyond work, I like diving into video games (especially strategy games), wandering malls or city spaces, and snapping photos of things that catch my eye. I also get experimental in the kitchen when inspiration (or hunger) hits.
