Über mich

Full-stack software engineer with strong expertise in building scalable web applications using React, Next.js, Node.js, TypeScript, and Python.

Specialized in API-driven platforms, system integration, and automation workflows. I design and implement scalable architectures by connecting systems, structuring data flows, and integrating external services via REST and GraphQL APIs.

Experienced in building headless web platforms using Strapi, Storyblok, and Drupal, as well as automating business processes using tools like n8n and Make.

In addition to hands-on development, I act as a technical advisor, supporting companies in structuring scalable architectures, improving system integration, and translating business requirements into maintainable technical solutions.

Currently expanding my expertise in AI-assisted development workflows (Claude Code), combining AI and automation to improve development efficiency and system design.
