About

I'm a frontend-focused developer with entrepreneurial drive, passionate about building accessible, performant web applications. My expertise spans React.js, Next.js, Node.js, and REST APIs, with a strong foundation in modern web technologies.

With experience in cloud databases (Supabase, PostgreSQL, MongoDB), API testing, automated UI testing, and production deployment, I bring a comprehensive approach to web development. I have a solid understanding of data structures and algorithms, open-source collaboration, and the complete journey from idea to production.

I do love writing, and write blogs
