Born in Seoul based in Paris
Software Engineer Specializing in
AI Agents/Generative AI Engineering
This is my philosophy as a Software Engineer.
With three years of experience in mobile and web development, I have mastered React, TypeScript, HTML, SCSS, and GraphQL—enabling me to build high-quality applications efficiently. My background in fine arts further enhances my strong understanding of UI/UX, allowing me to create intuitive and visually engaging user experiences.
Though I learned to code without tools like ChatGPT, I now belong to a generation that actively leverages AI in development. Over the past few years, I’ve witnessed how advancements in LLMs can dramatically accelerate the app development process and offer innovative solutions to complex problems. I build AI-powered tools such as chatbots using various LLMs, mainly with Python. I’ve developed applications with OpenAI, Anthropic, and Gemini models, leveraging tools like the OpenAI SDK and LangGraph to orchestrate multi-step agent workflows.
My focus includes prompt engineering, agent evaluation, and implementing guardrails to ensure responsible, stable, and effective AI integration in real-world applications. I’m also passionate about educating users on AI usage through clear documentation and in-app guidance, aiming to make intelligent tools both accessible and impactful.
