πŸš€ Working Set

πŸ“š Personal Study Log

πŸ§‘πŸ»β€πŸ’» Personal Projects

  • Model-Driven Infrastructure (MDI) Lab: The core implementation repository for the 'Beyond IaC' seminar, showcasing a practical architecture for validating infrastructure through YANG modeling. YANG-verified data seamlessly integrates with Terraform and Ansible to ensure predictable infrastructure deployments.

🏫 Woori FISA Cloud Engineering

2025.12.30 - 2026.06.25 (Expected)

  • Education & Training: Advancing comprehensive skills in Cloud-native DevOps and Enterprise Virtualization (ESXi/vCenter) through the Woori FISA Cloud Engineering program.

  • Log: πŸ“ Learning & Engineering Log

  • Projects

    • Technical Seminar - Beyond IaC: From Coding to Modeling with YANG: Computers see syntax, but we see data. I leverage YANG modeling to inject physical and logical boundaries into infrastructure data, ensuring operational trust is built on a foundation of data-driven order.

    • VMware TeamLab: An enterprise-grade virtualization project utilizing VMware ESXi and vCenter. Spearheaded the network and foundational infrastructure design to establish a robust environment for implementing advanced clustering features such as DRS, HA, vMotion, and vSAN.

    • Technical Seminar - VPN: Benchmarked the performance of WireGuard vs. OpenVPN and demonstrated infrastructure management cases using Tailscale (WireGuard-based SaaS), with a focus on operational considerations and optimization.

    • Learning Curator - n8n & Notion Refiner: A learning curator project that automates Notion database updates by orchestrating Notion and AI APIs through n8n.

    • Card Data Analysis with Elastic Stack (ES + Kibana): Analyzed real-world Woori Card datasets using the Elastic Stack to visualize consumption patterns by age group and derive data-driven customer acquisition strategies.

    • Java Stream API - Optimization Case Study: A performance-focused case study analyzing the impact of excessive intermediate operation usage within the Java Stream API on overall system efficiency.

🐧 Linux Home Server Setup & Operations

  • Live Status: πŸ“Š Server Status

  • Experience

    • ZFS & Data Management: Implemented ZFS to ensure data integrity through snapshots and managed high-availability storage pools.

    • NAS Optimization: Performed resource tuning and customized storage services within the OpenMediaVault (OMV) environment.

    • Secure Remote Access: Established a secure Private Mesh Network using Tailscale, enabling remote management without port forwarding.

    • Service Orchestration: Deployed and managed diverse self-hosted services using Docker containers for modularity and scalability.

  • Projects

    • Docker-2-Notion (D2N): Automation tool for real-time Docker container status synchronization with Notion API.

    • OMV 7 to OMV 8 Upgrade with ZFS & PVE: A comprehensive guide on migrating a ZFS-based NAS to OMV 8, specifically focusing on PVE kernel compatibility and system-level dependencies.
