I’m a software engineer at KFTC (Korea Financial Telecommunications & Clearings Institute), part of a team rebuilding legacy financial systems on a modern architecture.

I’m interested in how software design, testing, and maintainability change as AI writes more of the code—and what developers still need to own: boundaries, contracts, invariants, tests, and the structure that keeps a system understandable over time.

I write here about what I run into, rethink, and learn while building software.
