corecode:~$cat ./about.md
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.
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 actually shipped in all four domains — games, apps, AI and web. Top Finalist at Shinhan Financial Group's InnoBoost, the Shinhan Securities Vietnam website rebuild, and live services running in Vietnam are the receipts.
The people behind CoreCode
Founder · Full-Stack Developer
A developer with 15 years across web, mobile, databases and design. He worked on large SI and platform projects at LG CNS and Yahoo Korea, and today he still writes the plan and the architecture for every CoreCode product himself. Hands-on with E-E-A-T and SEO structuring in the financial domain.
Principal Engineer
An engineer who built systems and platform software at Tencent in China and Intel in the United States. He has worked both on server platforms that absorb heavy traffic and on low-level optimisation close to the hardware. At CoreCode he owns the final call on performance, reliability and infrastructure design.
What we use AI for — and what we refuse to use it for
Research, first-draft design, implementation and review — AI agents live inside every stage of our pipeline. Once the repetitive work moves into the pipeline, a small team covers far more ground.
Generated output is a candidate, not a result. Nothing ships unless it clears our numeric gates and a human review of the actual screen. Every hour AI saves us goes straight back into verification.
Knowledge-graph GraphRAG, grounding scores and output filters, layered together. This is a structure we run in production in finance and legal domains, where being wrong is not an option.
Frontier models, local models and dedicated vision models, allocated on cost and accuracy. Because we aren't locked to one vendor, a pricing or policy change never destabilises your service.
