KCMUSA - Korean Christian Mission USA

We built and operated a comprehensive portal platform for the Korean Christian community in the United States. We provided a digital hub for Korean churches and missionary organizations to share information in real time and communicate actively. Since 2002, we successfully operated various core services including sermon broadcasts, church information, free church website creation, church finder, and map services. We directly built and stably managed multiple dedicated servers — including web servers, media servers (sermon broadcasts), and map servers — to continuously provide high-quality services. Responsibilities (2004–2017): - Full programming and system development of the portal site - Server construction, operations, optimization, and security management - Service planning and continuous feature enhancement This was a large-scale Korean Christian portal that operated stably for over 13 years. We were responsible for the technical foundation and provided practical support for the ministries of countless churches and missionaries.
