Frontend Developer

I’m a Frontend Developer with a solid foundation in full-stack engineering, which allows me to design frontends that perform reliably and integrate smoothly with complex systems.

About me

Over the years, I’ve worked across the full stack — but I found my strongest impact and satisfaction in frontend development, where architecture, design, and user experience come together. I’m passionate about writing clean, efficient, and maintainable code that scales globally.

My core expertise includes Angular, TypeScript, JavaScript (ES6+), RxJS, HTML5, CSS3, and responsive web design. I’ve developed modern, scalable web applications with well-structured frontends that emphasize performance, maintainability, and seamless collaboration across teams.

By combining a frontend-first mindset with a full-stack perspective, I deliver high-quality, user-focused web applications that are fast, accessible, and easy to maintain — from UI to API.
