I'm a Node.js developer with a strong background in data collection, web scraping, and automation. I specialize in backend development using JavaScript and TypeScript, and enjoy building frontends with React when needed. Over the years, I’ve worked on high-load systems for extracting and processing structured data from websites and mobile apps. In my free time, I’m exploring Rust — drawn to its strictness and performance-oriented mindset.
