Full Stack Developer

Copenhagen, Denmark

Deloitte

Hi, I'm Charis

I'm a full stack developer from Greece, based in Copenhagen. I work at Deloitte, where I spend most of my time building and debugging front-end work for large multi-market web platforms.

Lately I have been writing a lot of TypeScript, React and C#.

Multi-brand web platform for a global food manufacturer

Sept 2025 – Present

  • Resolved production issues across 40 locales, covering broken locale routing, global redirects and contact form defects.

  • Built reusable React and TypeScript components for a shared library in a pnpm monorepo, using Radix UI and Tailwind CSS and documented in Storybook, built for rollout across the client’s brand portfolio.
  • Reduced promotional content load time by roughly 60% through lazy loading, caching and query optimisation.
  • Handled Contentful CMS configuration, Azure DevOps deployments and Azure Portal environment debugging.
