About Me

I am a passionate Fullstack Developer with over 4 years of experience in building scalable web and mobile applications. My journey started with a curiosity for how things work on the internet, which led me to dive deep into the world of coding.

I thrive in fast-paced environments and enjoy solving complex problems. Whether it's optimizing backend performance with Node.js or crafting beautiful UIs with Flutter and React, I bring dedication and attention to detail to every project.
