Experienced IT Professional and Tech Enthusiast
I am an experienced IT professional with over two decades of expertise spanning systems management, technical support, and digital transformation. My passion for technology began early, writing my first lines of code at age 14 and building HTML pages by 15, fueled by curiosity and a drive for innovation.
After earning a Bachelor’s degree in Computer Science from the University of Missouri – Columbia in 2001, I embarked on a career focused on delivering technical excellence. At Dana, a Fortune 500 company, I ensured the smooth operation of IT systems across office and production lines, managing server maintenance, backups, and disaster recovery.
Returning to Malaysia in 2008, I founded a company that helped over 100 businesses transition from paper-based processes to digital invoicing during the GST rollout. Along the way, I acquired accounting expertise, aiding clients in reclaiming nearly 1 million RM in tax returns. My efforts translated to over 16.5 million RM in client sales.
In addition to professional endeavors, I am deeply committed to exploring emerging technologies. I’ve worked on projects involving IoT, AI, and home automation, and even set up my own ChatGPT server using repurposed hardware. Hosting personal services like cloud storage and VPNs allows me to stay hands-on with the latest advancements while optimizing costs.
I’m a problem-solver at heart, blending technical knowledge with practical implementation. My ability to communicate complex concepts effectively ensures seamless collaboration with teams and clients alike. I am now seeking opportunities where I can apply my skills, continue learning, and make meaningful contributions to innovative organizations…Experienced IT Professional and Tech Enthusiast
