Summary
👤
Senior🎓
Top SchoolHeejune Kim is a senior support engineer with 11+ years of deep systems and kernel expertise, now at Microsoft after a decade building and supporting Windows desktop and embedded software. He excels in C/C++, assembly, device drivers and dump analysis, with a strong track record of stabilizing complex products—from KakaoTalk’s Windows client networking and accessibility to USB modem drivers and anti-cheat/security systems. Comfortable across user-mode and kernel-mode boundaries, he combines hands-on development, build automation (Jenkins, Python) and debugging to resolve thorny production issues. Notably, he has repeatedly bridged product and support roles—writing shell extensions, network daemons and updater/security components—so he brings pragmatic engineering that anticipates real-world failure modes. Based in Seoul, he pairs deep Windows internals knowledge with a practical focus on reliability and observability.
