01 / About

I’m Yakhyokhon — a full-stack software engineer based in Seoul, South Korea, building and shipping production-ready web and SaaS applications.

Currently running Ildiz Solutions, where I deliver client projects end-to-end — from architecture and development to deployment and post-launch maintenance. Previously an R&D engineer at Nuriflex, working on enterprise Energy Management Systems used in live production environments.

I care about systems that work reliably at scale, interfaces that feel effortless, and code that the next person can actually read.
