Quality Engineering Portfolio\n\nQuality Engineer with experience in **AI platforms, distributed systems, and automation-driven quality validation**.\n\nThis repository demonstrates how product quality issues can be analyzed, validated, and managed through engineering-driven QA practices.\n\nThe focus is on **Quality Engineering**, including:\n\n* system validation\n* test automation\n* CI/CD pipeline verification\n* quality metrics and release validation\n\nSensitive implementation details and internal architectures are intentionally omitted.\n\n---\n\n# Repository Overview\n\nThis repository is organized into four main areas.\n\n| Area                | Purpose                                  |\n| ------------------- | ---------------------------------------- |\n| Case Studies        | real-world quality validation examples   |\n| Automation          | test automation approaches and tools     |\n| Domains             | product domains and system types         |\n| Quality Engineering | testing strategies and quality practices |\n\n---\n\n# Validation Approach\n\nThe validation approach used across projects typically follows this workflow:\n\n```mermaid\nflowchart TD\n    A[System Change]\n    B[Risk Identification]\n    C[Test Strategy Definition]\n    D[Test Execution \u0026 Validation \u003cbr/\u003e#40;Automation / Smoke / API#41;]\n    E[CI/CD Test Execution \u003cbr/\u003e#40;Docker / Pipeline#41;]\n    F[Quality Metrics Review \u003cbr/\u003e#40;Coverage / Failure Rate#41;]\n    G[Release Decision]\n\n    A --\u003e B --\u003e C --\u003e D --\u003e E --\u003e F --\u003e G\n```\n\nThis approach helps ensure that testing activities focus on **high-risk areas and critical system behaviors**.\n\n---\n\n# Case Studies\n\nSimplified case studies based on real-world quality engineering work.\n\n| Case Study                           | Description                                        |\n| ------------------------------------ |
