corecode:~$cat ./about.md
A top-tier Korean engineering team — based in Vietnam
CoreCode is a Korean development studio with a legal entity in Ho Chi Minh City. Senior engineers from global tech companies design and build here, on the ground.
What we do
Finding a development partner you can actually trust in Vietnam is hard. CoreCode exists to close that gap — top-tier Korean engineers, working locally in Vietnam. Our Ho Chi Minh entity handles contracts, VAT invoicing and local operations, while the quality bar on the work itself stays the one we held at Korea's largest enterprise projects.
Our team came through LG CNS, Yahoo Korea, Tencent and Intel. We've run platforms that absorb serious traffic and optimised systems close to the hardware, which is why we never hand the architecture to someone else. Planning, architecture, implementation and operations stay with the same team, so nothing gets lost in translation and no one disowns the result.
We have shipped or operate real work in all three areas — enterprise AI, Vietnam web and apps, and Apps in Toss. Top Finalist at Shinhan Financial Group's InnoBoost, the Shinhan Securities Vietnam website rebuild, and live services running in Vietnam are the receipts.
