About Me
"Combining the speed of AI with the depth of an engineer to build polished solutions." I actively adopt the latest AI tools like Claude Code to lift development productivity, while keeping the fundamentals sharp — reading and working with the code directly rather than depending on what the tools produce. Beyond simple code generation, I study optimal workflows that improve the accuracy and efficiency of AI use through agent harness design. In particular, I follow Anthropic's 4D Framework (Delegation, Description, Discernment, Diligence) — responsibly reviewing AI output and stepping in directly to see system stability and completeness through to the end. Grounded in this technical attitude, I move fearlessly across the boundaries of technology — from maintaining complex legacy systems to building modern AI services on RAG and LangChain. With insight earned across the full development cycle, I aim to be the developer who turns new technical currents into business value the fastest.
