Projects
Professional backend, delivery, analysis, and incident-response projects, plus current public repositories.
Back to AboutThese projects cover backend development, delivery environments, data analysis, and operations. Professional entries describe their period and contribution. For personal work, the three linked repositories describe their current scope; the template collection is described in my public profile.
Professional projects
- Incident response process — Defined incident severity, response roles, recovery steps, and follow-up.
- Web-based avatar sign-language service — Built APIs and the NCP Kubernetes delivery environment for a public-sector SaaS service.
- Content production platform modernization — Reworked content state, search, and asynchronous processing.
- Sign-language matching and data analysis — Compared audio, STT output, and delivery results to investigate matching errors.
- Emergency notifications for deaf users — Processed CAP XML alerts and delivered notifications by user preferences and region.
- Barrier-free museum kiosk backend — Developed content APIs and integrations for sign-language, audio, and Braille kiosks.
- Multi-cloud and on-premises monitoring — Connected metrics, dashboards, and alerts across cloud and on-premises environments.
- Sign-language notification service maintenance — Maintained the path from audio and STT to sign-language matching and notifications.
- Initial sign-language content platform — Built content CRUD, upload and state handling, and animation-module integration.
- KRGDB genomic database — Contributed to genomic preprocessing, variant analysis, and annotation for 1,722 Korean people in KRGDB.
Personal projects
- hy-home.docker · Compose home infrastructure — Maintains layered Compose definitions, explicit profiles, and operating procedures.
- hy-home.k8s · Local Kubernetes and GitOps — Manages a local Linux, Docker, and k3d platform through ArgoCD.
- hy-home.Learned · Reusable learning notes — Connects dated TIL notes and experiments with Python tooling, tests, and documentation.
