ABOUT CODEMARU
Solving real problems,
one at a time
CodeMaru is an independent development studio run by Minsu Jang. We go beyond attractive prototypes to build, operate, and continuously improve services people can actually use.
WHY CODEMARU
Built from necessity,
validated in operation
CardHybrid began with the need to share business cards more easily, while Families was created to preserve family memories privately.
We solve field problems the same way, from equipment interfaces and databases to CCTV monitoring. Lessons from production become reusable open-source capabilities in Dreamine.
Designed and built in-house
We understand the problem, design the structure, and own everything from interface to data and deployment.
Operated in production
We observe failures and user flows directly and validate our work with functioning results.
Continuously improved
We make steady improvements using user feedback and operational data.
WHAT I BUILD
Connecting web, desktop,
and the real world
We design the complete flow that keeps a service running, not just a single screen.
