Hello! I am Dmytro, a Fullstack Developer focused on building reliable and high-performing web applications. I combine strong Frontend skills (React ecosystem) with solid Backend knowledge (Node.js, SQL) to deliver complete, "turnkey" projects.

Currently pursuing a degree in Cybersecurity, so I prioritize data protection, secure authentication, and stability in every solution I build.

🚀 What I can do for you:

1.  Frontend Development: Building interactive interfaces using React.js and Next.js. Creating pixel-perfect, mobile-first layouts.

2.  Backend Engineering: Developing RESTful APIs, configuring servers (Node.js/Express), and managing databases (MySQL, PostgreSQL).

3.  E-commerce Solutions: Integrating payment gateways (e.g., Vivo), shopping carts, user dashboards, and secure JWT authentication.

🛠 Technical Stack:

• JS Stack: React, Redux (Toolkit), Next.js, Node.js, Express.

• Data: MySQL, SQL, MongoDB.

• Tools: Git, Docker, Postman, Webpack/Vite.

My Approach:I am result-oriented with experience in both freelance projects and corporate environments (Aromatika). I guarantee transparent communication, adherence to deadlines, and clean, maintainable code.
