Full-Stack Engineer · Founder · AI-Assisted Development

I build software that humans and AI can both understand.

I'm a Full-Stack Engineer with 8 years of experience and the founder of a software development company based in Korea.

I specialize in building and improving SaaS products—from frontend to backend, database design, cloud infrastructure, and long-term maintenance.

Rather than simply delivering features, I focus on creating products that are easy to maintain, scale, and hand over to future developers.

• 🚀 Build modern SaaS applications
• ⚛️ Develop scalable React / Next.js frontends
• 🛠️ Design reliable backend APIs with Node.js
• 🗄️ Design maintainable PostgreSQL databases
• ☁️ Deploy and operate services on AWS
• 🤖 Integrate AI into real-world products and development workflows

AI is part of my daily workflow—not to replace engineering, but to improve engineering.

I use AI to:

• Accelerate development
• Organize project knowledge
• Produce clear technical documentation
• Keep codebases easy for future developers (and AI) to understand

Frontend

React · Next.js · TypeScript · Tailwind CSS

Backend

Node.js · Express · REST API

Database

PostgreSQL · Supabase · MongoDB

Cloud & DevOps

AWS · Docker · GitHub Actions

Tools

Git · Figma · Claude Code · ChatGPT · Cursor

Most of my professional work is developed under private repositories due to client confidentiality.

My GitHub primarily contains personal projects, reusable tools, and experiments that I can share publicly.

Build software that is easy to understand, easy to maintain, and ready to grow.

Thanks for stopping by! 🚀
