Engineer who loves building cool stuff and helping others learn
I'm a Frontend Engineer with 8+ years of experience working with modern JavaScript, React, TypeScript, Next.js, MUI, CSS, HTML, TailwindCss, and a lot more.
I've worked as a teacher and mentor before, and it's something I'm truly passionate about. I love building clean, accessible UIs and enjoy helping developers at all levels grow with confidence.
