Sangwan Jeon전상완, EngineerWork spans product development, infrastructure, and operations, with an emphasis on software that stays useful and maintainable after launch.
Engineering is most rewarding when a program or system makes someone’s work noticeably easier. That means removing avoidable effort and making complex tasks easier to understand and act on.
Products, operations, and infrastructure are treated as one connected system. Work starts with the people closest to the problem, uses testing and automation to reduce repetitive work, and leaves clear documentation so others can build on it.
Worked as a Frontend Engineer at NGINE STUDIOS, a subsidiary of NEXON Korea. Built internal web solutions to grow the active user base of NEXON games and help employees work more efficiently. Collaborated with NEXON’s Platform Division, formerly Intelligence Labs, on product development, infrastructure setup, and operations.
Worked as a Frontend Engineer on Planetarium’s Publishing Product Team, with a focus on improving the player experience and increasing daily active users for Nine Chronicles, a fully decentralized game.
Worked as a Full Stack Engineer on a home-buying information service. Measured the effect of OpenGraph link previews on sharing, analyzed user journeys with Datahog and Sentry, and used the findings to improve the conversion funnel.
Worked as an intern on infrastructure for both air-gapped, on-premises products and internal systems. Gained hands-on experience building and operating enterprise environments.
Technical lessons from deployments and operations are shared through writing, alongside reusable open-source tools. A UbuCon Asia 2022 talk covered the implementation of a real-time clubroom occupancy service. Other knowledge-sharing work includes Docker seminars and infrastructure study sessions.
