Summary
🤩
Rockstar🎓
Top SchoolJunhyuk Choi is a backend engineer and manager based in Seoul with eight years of hands-on experience building and operating cloud-native services for a PropTech startup. He joined as the first backend hire and grew into a leadership role, owning API, DB, CI/CD, observability, and migration efforts that enabled national expansion and secured Pre-Series A traction. Junhyuk has extensive full-stack backend expertise—TypeScript/Node.js/Nest.js, PostgreSQL/PostGIS, Redis, Elasticsearch—and has led large-scale migrations (GCP→AWS RDS), Kubernetes/EKS adoption, and ArgoCD-driven CI/CD consolidation. Notably, he improved data processing and API performance dramatically (200%+ data pipeline speedup, API latency reduced from ~500ms to <100ms) while also designing DB security and multi-tenant auth/SSO systems. He combines pragmatic engineering with operational rigor, running internal dev studies and serving as both project manager and hands-on implementer for realtime features, payment flows, and private-network integrations.
