About Chinthaka

am a Full-Stack Developer who specializes in building lightning-fast, highly scalable web applications. By combining modern JavaScript frameworks with robust content management systems, I deliver websites that are incredibly fast for users and incredibly easy for you to manage.
My sweet spot is Headless WordPress—giving you the familiar, user-friendly WordPress CMS dashboard for publishing content, while utilizing React and Next.js on the frontend for unmatched speed, security, and SEO performance.
Beyond CMS development, I am highly experienced in the full MERN stack (MongoDB, Express.js, React, Node.js), allowing me to build completely custom web applications, dynamic dashboards, and secure RESTful APIs from the ground up.
Core Expertise:
Frontend: React.js, Next.js, Modern UI/UX, Tailwind/Bootstrap
Backend & Full-Stack: Node.js, Express.js, MongoDB (MERN Stack)
CMS & Decoupled Architecture: WordPress, Headless WordPress (WPGraphQL), API integrations
Whether you are looking to migrate a sluggish WordPress site to a blazing-fast Next.js frontend or need a custom MERN application built from scratch, I write clean, maintainable code to bring your vision to life."
