About

Hi, I'm Charris.

Charris Kefallinos, full-stack web developer in Athens

I'm a full-stack web developer based in Athens, Greece. I build custom websites, e-commerce stores, and web applications, bringing frontend and backend development together to deliver complete digital solutions from planning to production.

I have extensive experience with demanding e-commerce and web projects using WordPress, WooCommerce, Magento, Next.js, React, Node.js, and PHP. I prioritize clean architecture, high performance, maintainability, and scalable systems that evolve with your business.

I start by thoroughly understanding the problem, then recommend a practical technical approach, free from unnecessary complexity or restrictive solutions.

  • Tailored solutions, not one-size-fits-all templates
  • Performance and solid architecture
  • Communication in Greek and English
