"Make Humans More Creative"

About Me

my Face

I'm GeonHee Lee (you can call me Jason), a student developer at Daegu Software Meister High School (DGSW) .

I believe human time and creativity should never be wasted on repetitive work. With the rise of LLMs, the line between “what machines should do” and “what humans should do” has become clear.

Through projects like Sync, Commitly, and Exam Buddy PT, I’ve been building AI-powered systems that automate what machines can handle—so humans can focus on creative problem solving and critical thinking instead.

I specialize in full-stack development using TypeScript, Python, and Kotlin, with a focus on scalable backends built on FastAPI and AI architectures using LangGraph and vector databases.

What I'm Working On

I'm currently leading Sync, an AI-powered project management SaaS that bridges communication gaps between developers and non-developers. It automates issue creation, ERD generation, and scheduling through a custom LLM architecture.

Previously, I built Commitly, a tool that automatically writes daily retrospectives, helping developers focus more on creating and less on documenting.

My Interests

I’m passionate about LLM frameworks like LangGraph and MCP, exploring how autonomous reasoning and structured workflows can reshape software development. I’m especially interested in building AI systems that collaborate with humans—not replace them.
