Summary
Software consultant and technical publisher (author, translator, reviewer) with nearly 30 years of experience in the IT industry. Currently, I am deeply focused on AI application development, specializing in LLMs, AI agents, and drone/robotics convergence.
Proven ability to master complex technologies, demonstrated by authoring and translating numerous books on LLM API development, LangChain, and machine learning. My practical skills are primarily built through hands-on personal projects, including developing LLM-based tools, AI integrations (e.g., Claude Skills, MCP servers), and automation scripts.
These applied skills have also been formally recognized in university-level AI competitions. Having earned a BEng in Drone and Robot Engineering, I am now further deepening this specialization through a Master’s program in AI Convergence Technology.
