Reponsibilities and achievements:

• Slider Scrap and Yield:
  Focus on managing and improving yield while reducing scrap costs related to slider production.
  Conduct quarterly POR (Plan of Record) yield projections for both legacy and new HAMR (Heat-Assisted Magnetic Recording) products.
  Hold weekly yield meetings with the slider team to review yield improvement projects related to ISI (Inter-Site Inspection) and mechanical aspects.
  As a CRB (Change Review Board) member, review process engineering changes, provide feedback, and assess risks and quality impact.
  Factory Control System (FCS):
  Oversee the implementation and optimization of factory control systems.
  Detect and contain anomalous parts or equipment for disposition.
  Minimize the search space for engineering by assisting in RCA (Root Cause Analysis).
  Act as an intelligent agent between data and subject matter experts (SMEs).
  Notably, managed to reduce third-party software costs from $1M to $255K within 2 years by sharing resources with the GFIT team.
  In FY23, cost reduction efforts included reducing Savigent US resources, transferring knowledge to local Thai resources, and zeroizing Savigent T&E expenses.
  In FY24, supported critical tools for HAMR (Heat-Assisted Magnetic Recording), including new HAMR-specific tools and MSMR/PMR critical tools.
  For FY25, the plan is to migrate to an open-source solution (EDS/TDL) for data collection.
  Scrap Cost Management:
  Focus on controlling and reducing scrap costs for slider operators.Address both yield-related and non-yield-related issues.
