Head of UX

2021 - 2023

Senior Product Designer

2018 - 2020
  • Redesigned a form builder in a content management system, enabling the operations team to easily make changes to forms without relying on engineers. The registration form had been manual, and it became unscalable as the company expanded quickly.
  • Refined the deposit management feature in Grab's rental product tool. The sales team needed to manage customers' deposits, including taking, refunds, and offsets, and the finance team needed to see the holistic view.
  • Facilitated workshops with eight country representatives to align with the rental business' vision in the next few quarters and on how the product team can help out with their current pain points.
  • Added new features to improve the photo editor in Grab's internal reviewing tool, allowing the reviewing team to check the legitimacy of the documents that the drivers had sent online.
  • Improved selfie checks to reduce incidents and complaints about matched drivers being incorrect because registered drivers had rented out their accounts to non-registered drivers. The registered drivers were suspended.
  • Played a key role in interviews and hiring designers to work for Grab. Mentored and trained a junior designer intern and a researcher to work on Grab's acquisition platforms.
  • Guided and cultivated junior designers to be better product designers by supervising their work processes and checking on their progress fairly regularly without micromanaging.
  • Facilitated one-on-one reviews with designers to provide feedback on their vision as a designer and their progression and receive feedback on how I could improve as a manager and mentor. I would also report on this to my line manager.
  • Organized administration and logistics for junior designers in terms of contracts, annual leaves, and overseas travel.

  • Integrated and executed flow, UI, and UX for an English learning app for the Japanese market together with engineers and the COO of the company, who was also acting as a product owner.
  • Directed the content team (including contractors) to maintain consistency and quality of the language used across the app because the main focus of the app is to have a conversation with the AI.

  • Facilitated workshops and design sprints to improve the UX of the app.
  • Mentored and trained a junior designer to work on the design guidelines for TerraTalk.
  • Fostered our more junior Japanese designers to exercise more critical thinking when working on our product and taught them how to not be afraid to ask questions. They presented their work to me before we presented it to senior stakeholders.
  • Guided our graphic designer and marketing team to design our marketing material to be more digital-friendly and inspired the whole team to create a youth branding for our product.
