Jookwang(JK) Jung
Engineering Leader | 20+ Years of High-Availability Infrastructure | AI Agent & MCP Pioneer
JK Jung · Los Angeles
I am an engineering leader who has spent two decades at the intersection of extreme-scale infrastructure and rapid product innovation. From architecting mission-critical databases for massive MMORPGs to founding AI-driven fashion platforms, my career has been defined by a single mission: translating advanced technology into tangible business value.
Currently, I am focused on the frontier of Generative AI and Autonomous AI Agent systems. I don't just build models; I orchestrate intelligence to solve real-world problems—whether it's reducing operational overhead by 90% through GenAI or digitizing legacy workflows into automated ERP ecosystems.
What I Bring to the Table
AI-First Engineering: Deeply specialized in Model Context Protocol (MCP) and AI Agent orchestration to accelerate the software life cycle from ideation to production.
0→1 Product Execution: Proven track record of building engineering organizations and product architectures from scratch as a Founding Head of Engineering.
Scalable Infrastructure Mastery: A deep-rooted foundation in large-scale MySQL/PostgreSQL (100M+ rows), high-availability systems (99.99% uptime), and global cloud architecture (AWS) across the U.S. and Asia.
Business Impact Mindset: I thrive where Engineering meets Strategy, ensuring every line of code accelerates go-to-market efforts and scales business impact.
I am passionate about how AI will reshape enterprise software and human productivity. If you are looking for a leader who can navigate both the complexities of legacy scale and the AI frontier, let's connect.
