Senior🎓
Top SchoolHyunwoo Jung is a versatile software engineer with 10 years of experience building systems that span operating systems, distributed storage, machine learning, web backends, mobile apps, and 2D/3D game clients. Currently at Toss Bank, he brings a research-driven approach from his Ph.D. and master's work at KAIST, where he designed tiered memory management and distributed metadata servers for data center storage. He has shipped production mobile and backend services in Java, Python, and Ruby as well as performance-critical C++ game and CI systems, demonstrating fluency across low-level and application-level stacks. His academic projects include a retention agent for scalable episodic memory networks and Linux kernel integrations—work that blends ML intuition with systems engineering. Based in Seoul, he combines rigorous research instincts with practical product delivery, often translating theoretical ideas into kernel patches and production services. Colleagues note his uncommon ability to move between kernels, cloud services, and user-facing apps while maintaining a focus on performance and scalability.
