Senior Full-Stack Developer | Next.js, React & Tailwind CSS Expert

Greetings! I am a dedicated digital entrepreneur, general physician, and software developer managing CalcKing.app, a live multi-tool platform hosting over 130+ active computational utilities serving global traffic.

With deep production expertise in Next.js, React, and Tailwind CSS, I engineer clean, high-performance, and mobile-first web experiences. My work spans from building advanced dynamic dashboards to launching intricate logical models—such as technical biological calculator systems featuring highly granular heartbeat and breath-count analysis.

I combine data-driven architecture, robust backend workflows using Google AI Studio and Firebase environments, and clean frontend design to deliver software solutions that scale. If you are looking for maintainable code and an experienced developer who understands end-to-end digital optimization, let’s collaborate to build something exceptional.
