Experience

  • 2025.10 - 2026.04
    Software Engineer
    Fuyao Glass America Inc.
    • Fine-tuned YOLOv8 for inline automotive-glass inspection on labeled line-camera frames, reaching mAP@0.5 ≈ 0.87 and >90% recall on held-out images under plant miss-rate targets.
    • Built Python/SQL pipelines that fuse defect detections with coating, tempering, and inspection signals into a shared analytics layer; shipped role-based dashboards tracking OEE, FPY, scrap, and changeover to support high-efficiency production.
    • Productionized defect detection on line-camera frames with cron, alerts, and access control — 99.3% job success and 2.4 hrs/week less downtime; ran A/B and DOE setpoint studies in Jupyter for process tuning.
  • 2024.10 - 2025.10
    Software Engineer
    4Pexonic Inc.
    • Developed an academic impact analysis platform tracking citation patterns across tens of thousands of records using Node.js, MongoDB, and Next.js with Docker, serving university researchers and policy institutions.
    • Built two-tier caching (in-process LRU + Redis), cutting median and p95 latency by 40%.
    • Integrated gRPC microservices; implemented bcrypt/session auth and Nginx TLS.
  • 2023.10 - 2024.10
    Research Engineer
    UCSD Halıcıoğlu Data Science Institute
    • Built modular Python Injector pipeline (generate → sample → inject → eval) with beam-search + Optuna/TPE, cutting downstream AUC by >0.25 vs. random attacks.
    • Co-authored SAVAGE (PVLDB'25), designing corruption dependency graphs and bi-level black-box search to model mechanism-aware missingness, selection-bias, and outlier patterns for pipeline-level stress-testing of ML systems.
    • Ran Inject → Clean → Retrain benchmarks across missing-value, selection-bias, and outlier scenarios to evaluate state-of-the-art cleaning, debiasing, and UQ pipelines and expose their data-centric robustness gaps.
