Work

  • May 2018 - Nov 2018
    Intern
    SINAPSE
    • Used Principle Component Analysis (PCA) and Linear Discriminant Analysis (LDA) in Matlab to reduce dimensions of large datasets and perform classification analysis.
    • Datasets consisted of spike trains of neurons in monkeys' brains that were recorded as they performed a working memory task.
    • Simple classification analysis was used to understand the mechanism of neurons during the engagement of working memory.
  • Jun 2019 - Jul 2019
    Intern
    DBS Bank
    • Contributed to the building of an acquisition model for Paylah! customers in the Consumer Banking Analytics department.
    • Used SAS and SQL to extract and create the variables discussed from the DBS database.
  • Aug 2019 - Dec 2019
    Intern
    Axis Capital
    • Worked full-time under the Catastrophe Modelling (CAT) team in re-insurance.
    • Ran Catastrophe models and performed preliminary analytical reports using industry-specific software.
    • Used various internal tools to assist the pricing process within the CAT team.
    • Created tools and scripts with Python to ease the process of data extraction for use in the model and analysis.
  • 2021 - 2023
    Full-time Industrial Engineer
    Murata Electronics Singapore
    • Performed data analysis for the cost management of the manufacturing of ceramic capacitors.
    • Innovated new methods to understand the cost structure and effectively manage profit/loss statements.
