Full-stack engineer based in Seoul. I work mostly in TypeScript: NestJS on the back end, Next.js and React on the front, with PostgreSQL, MongoDB and Redis behind them.
I ship things people actually use. A halal grocery marketplace that has been live and taking orders since early 2026. A restaurant POS that rang up over 6,000 orders in its first months and now runs daily in a working kitchen. I also build AI into products: tool-calling agents, RAG retrieval, and LLM integration with key-level failover.
Constraints are where I do my best work. One POS had to run in an 80MB footprint on a 2GB machine, fully offline-first, so every design choice traced back to that. I build with Claude Code for agentic scaffolding and move quickly without breaking the parts that matter.
Available for remote contract work, backend or full-stack. Happy to hop on a call and talk through your problem.

I built Pizza House as a full-stack project with a carefully designed architecture, separating the system into three distinct applications. The foundation is a powerful backend API developed with Express.js, which serves as the central hub for all data and logic. It handles everything from user and admin authentication to processing RESTful API requests and managing file uploads for product images via multer.
This backend supports two separate front-end applications. For customers, I created a modern single-page application using React and Redux for smooth state management. This allows users to seamlessly browse the menu, view product details, manage their orders, and edit their profiles. For the restaurant’s staff, I developed a secure, server-rendered admin panel. This traditional application provides administrators with complete control over the platform, allowing them to add or update menu items, manage product photos, and oversee all user accounts.
The entire system is fully functional and ready for deployment. I would be delighted to provide a live demonstration to showcase its features and technical details in greater depth and would love to show other projects as well.
