1. Software Design Defect Analysis & Resolution

• Identify architectural anti‑patterns in existing codebases and perform root‑cause analysis
• Trace root causes of hard‑to‑reproduce defects such as performance degradation, memory leaks, and concurrency bugs (race conditions, deadlocks)
• Quantify technical debt in legacy systems and build a risk‑prioritized improvement roadmap
• Propose actionable redesign solutions—including backward‑compatibility and migration strategy—rather than purely theoretical proposals

2. Design & Management of Software Stability Assurance System

• Develop in‑house static‑analysis diagnostic rules and integrate them into the CI pipeline
• Design tiered severity quality gates and enforce them in the build process
• Design suppression/waiver governance policy—format validation, deadline management, and automatic severity escalatio...
