Where errors are not an option,
we build things that work.

A Korean development team incorporated in Ho Chi Minh City. AI for finance and law, websites and apps for businesses entering Vietnam, and Apps in Toss mini apps — we deliver systems that run, not demos.

Korea × Vietnam

Work with a top-tier Korean engineering team — on the ground in Vietnam.

CoreCode is a Korean development studio with a legal entity in Ho Chi Minh City. Engineers who came through LG CNS, Yahoo Korea, Tencent and Intel design and build here, locally. No time-zone gap, and the same quality bar we held at Korea's largest tech projects.

Expertise

Strategy, design, engineering and operations under one roof.

We don't subcontract your project to someone else. Planners, engineers and our AI pipeline sit on the same team, so the people who scoped it are the ones who ship and run it.

02 / How we workHow we work

AI builds. People decide.

AI outputs are candidates. We release only what passes quantitative gates and visual review.

Orchestrator + workers

An orchestrator responsible for design and verification assigns tasks to coding, interpretation, and assembly workers, and moves on only after checking the results directly.

Quantitative gates

We set measurable gates first: builds, tests, accuracy, and performance scores. Anything that fails remains in the report with its numbers.

Visual review

Some things look wrong on screen even after passing every numerical gate. We inspect the actual screen, reject, and rerun — we have a record of rejecting one character four times.

Collaboration with a record

Work records show who did what and when. Clients raise issues and receive the results.

AI makes us several times faster, but people decide what ships. Every hour CoreCode saves with AI goes straight back into verification.
