Byoung-Hoon L.

AI Data Expert & LQA Specialist (Freelance)

I have built a distinguished career spanning over 30 years, successfully navigating three distinct industries: IT, Construction, and AI. My proven track record across these diverse fields demonstrates my adaptability and drive for excellence. Phase 1 (1994–2013): IT Sales & Marketing Expert For 19 years, I specialized in the IT software sector, focusing on e-learning, RBMS (Rule-Based Management Systems), and X-Internet technologies. I led the successful launch of 'GVA,' Korea's first e-learning system, and managed B2B sales for major financial institutions such as Kookmin Bank and Samsung Life. My expertise extends from creating technical manuals to conducting high-level press briefings and marketing strategies. Phase 2 (2013–2024): Construction & Process Management Transitioning from IT to the architectural field, I excelled as a Site Manager, overseeing complex renovation and interior design projects. I successfully delivered high-profile projects, including the Ahn Jung Geun Memorial Hall, achieving a record of zero accidents and strict adherence to schedules. My success in this phase was built on rigorous process management and deep trust established through constant client communication. Phase 3 (2024–Present): AI & Dual-Track Professional I operated an interior design company as a specialized Task Force (TF). Currently, I am leveraging this diverse background as an AI Freelancer. I actively contribute to the AI data ecosystem through roles in Korean Voiceover, Language Quality Assessment (LQA), Natural Language Processing (NLP), and Data Annotation, proving my capability to adapt to cutting-edge technologies. I always work with a lot of curiosity and try to find the most efficient way. This effort is stronger, more desperate, and I have the confidence to do better. Thank you.
