Hello! I'm Nisal Jinadasa, a Full Stack Developer based in Colombo, Sri Lanka. I specialize in building modern web applications using React, Node.js, and AWS cloud services.
Currently developing healthcare and fintech solutions at AMERCK, where I've launched an EMR system processing 700+ weekly e-prescriptions and built AI platforms handling 2,000+ requests per second.
When I'm not coding, I enjoy helping startups transform their ideas into scalable web applications and staying up-to-date with the latest in web development and AI technologies.
