Available for backend work
Backend developer who ships practical APIs and keeps the details boring. Slow? Fixed. Fragile? Hardened. Not deployed yet? Built.
I work closest to backend systems, infrastructure, and the product edges where reliability actually shows up.
Most of my recent work has involved Claude Code, Codex, and harness engineering. I focus on tightening development automation and repeatable verification flows.

NooooK Studio
Migrated the ReadingGarden app backend from Python/Django to Kotlin/Spring Boot and moved the entire infrastructure from AWS EC2 to Oracle Cloud A1. Joined the dog and cat care management app from the planning stage and own its backend (currently in planning).

NailTocToc
Designed the initial backend and infrastructure architecture and built the entire AWS EKS Kubernetes infrastructure single-handedly (ArgoCD GitOps Blue-Green, Terraform IaC). Contributed broadly across all seven microservices, supporting stable operations and quality across the platform.

Mining5000
Single-handedly drove three client projects end to end — from on-site sales meetings and initial PoC to requirement design and development. Delivered Clova OCR/OpenAI data processing, Pinecone-based collaboration recommendations, and RPA automation.

Arffy
On the Arffy team project, built the backend for a vintage lighting store. As one of two backend developers, I owned all user-facing APIs — order concurrency control with pessimistic locking, personal-data encryption via JPA Converter, JWT/Kakao OAuth, and PortOne payments — and operated the live service for nine months.
Always open to a practical build, a backend cleanup, or a production problem that needs a calm pair of hands.
