About Me

I'm a passionate Full-Stack Developer and Software Engineer with 3+ years of professional experience building scalable, high-performance web applications. Having completed my Master's in Computer Science (Software Engineering) at the University of Wollongong, I bring a strong blend of academic excellence and real-world engineering expertise.

I specialise in React.js, Next.js, Node.js, and cloud-based solutions. I've successfully delivered 50+ projects on Fiverr with 100% client satisfaction, and developed a full-scale Medical Supplier Management System for a US-based client, reducing admin workload by 60% through smart automation.

I thrive in agile environments, enjoy solving complex problems, and am always eager to learn and contribute to meaningful projects.

Currently: Master of Computer Science Graduate @ University of Wollongong + Open to Opportunities
