Professional summary

Junior Frontend Developer focused on web development and local business digitalization. My primary focus is to solve real-world needs by building landing pages, QR systems, efficient forms, and maintainable digital workflows that deliver immediate value.

I combine a solid technical foundation in HTML, CSS, JavaScript, and React with a professional Git workflow (branches, PRs, reviews) and the active use of applied AI tools (such as Claude and Lovable) to accelerate development and document rigorously.

I am drawn to technology when it solves concrete problems for people and local businesses, bringing visual clarity and operational simplicity instead of unnecessary complexity.
