About Me

I'm a Front-End Developer with a strong passion for problem-solving and a keen eye for detail. My focus is on building blazing fast, robust and responsive websites, that provide users with seamless experiences. I enjoy using cutting-edge technologies and continuously learning to enhance my skills.

With 2 years of experience in front-end development, I have contributed to various open-source projects and worked with frameworks like React, Next.js, and Astro. I also enjoy working with back-end technologies and have experience with Node.js, Express and databases like PostgreSQL and MongoDB.

I believe in continuous improvement and am always looking for new ways to grow and contribute to the tech community. When I'm not coding, you can find me diving deep into the wonders of astrophysics or enjoying beautiful iconic and high-performance cars.
