Summary
Dexter Jung is a pragmatic software engineer and technical leader with 9 years of experience building backend systems, search infrastructure, and scalable services across Ruby on Rails, Java/Spring, and C# ecosystems. He led Jobplanet’s backend growth from 4 to 15 engineers, introduced onboarding and healthy development cycles, and guided a gradual migration from a monolith to microservices while owning authentication, payment, and news services. A specialist in search and crawling, he built integrated crawlers and drove Elasticsearch migrations and Korean-language search improvements using user dictionaries and morphology tooling. He combines hands-on troubleshooting and performance tuning (New Relic, DB indexing, caching) with cross-functional collaboration and documented knowledge transfer to stabilize legacy “black box” projects end-to-end. He speaks and writes on developer topics and has a track record of turning undocumented, risky services into well-documented, teachable systems. Based in Gyeonggi, South Korea, he’s focused on becoming a balanced CTO who equally values people, process, and technical craftsmanship.
