At Creobit, I built and operated Skorohod, a VPN subscription service, as the sole engineer. I handled payments, automatic configuration delivery, user and device management, and HAProxy across three servers in two countries; the service reached about 3,000 users.
I also moved local builds to centralized CI/CD, cutting release build times from 1–2 hours to 15–20 minutes. On a project called Hanjaro, I built a Telegram bot that uses dictionary data, Unicode Unihan data, and an LLM to explain Korean words and their Hanja roots.
