Top SchoolYumin Wong is a Staff Software Engineer based in Singapore with 11 years’ experience building production-grade platforms and developer tools at GitHub and other fast-moving companies. At GitHub she’s driven high-impact projects in the Copilot org, merge-queue tooling, and a Production Timeline that helps Incident Commanders quickly correlate incidents with deploys and feature changes.

Her background spans backend Rails services, API gateway design, and payment/finance integrations, reflecting strong cross-functional collaboration with product, finance, and support. Outside of product work she mentors and leads in the community (Women Who Code Singapore, Code Platoon), signaling a commitment to developer growth and inclusion. Colleagues know her for thoughtful operational tooling and a knack for turning messy incident data into actionable timelines.
