What I'm looking for

I'm seeking a collaborative IT or content-moderation role where I can apply Windows/Linux administration, AI data labeling, and QA skills, with opportunities for growth and cross-cultural teamwork.

I am an IT professional with a Computer Systems Technician diploma and over six years of experience in technical support, AI data labeling, and content moderation. I have hands-on expertise in Windows/Linux administration, Cisco networking, and virtualization (VMware, Hyper-V), and I improved NLP model performance by reducing error rates by 15%.

I manage high-volume workflows—reviewing 200+ AI responses daily and driving 95%+ timely case resolution—while building reporting systems and QA processes. I bring strong cross-cultural communication in English and Korean and seek roles that combine technical troubleshooting, data annotation, and quality assurance.
