Summary
👤
Senior🎓
Top SchoolKyubum Choi is a backend-focused software engineer with 10 years of experience building scalable web and cloud-native systems across startups and product teams in South Korea. He’s fluent in a wide polyglot backend stack—Python/Django, Node.js (Nest/Express), Go, Java Spring, Ruby on Rails, and Elixir—and pairs that with production experience in PostgreSQL/MySQL/MongoDB, Redis, Elasticsearch, RabbitMQ, Docker, and Kubernetes. Kyubum has led teams and co-founded a startup (PIPER), owned end-to-end architecture and CI/CD, and shipped data-intensive features like esports analytics, metadata crawlers, and signature crypto research. He moves between building APIs, migrating storage backends, and operating sharded clusters, showing both hands-on engineering and operational ownership. Now at UNITBLACK after recent tenures at Lemonbase and QWER.GG, he combines practical DevOps skills with a product mindset and an appetite for embedded and mobile experiments (Raspberry Pi, Android, React Native, Flutter). An understated strength is his track record of migrating legacy data and services to more robust architectures while keeping teams productive.
