Summary
🤩
RockstarCliff Koh is a seasoned software engineer and technical leader with 14 years of experience building reliable, scalable systems across Microsoft, Goldman Sachs, Grab and GovTech Singapore. He has driven high-impact projects from front-end component libraries (early Office UI Fabric / Fluent UI contributor) to critical infrastructure such as Fabric Bot for GitHub automation and auto-scaling on Goldman Sachs’ PLEX platform, with demonstrated reliability in production. Comfortable as an individual contributor and as a mentor, Cliff repeatedly turns operational pain points into automated, widely adopted services while maintaining high uptime with minimal headcount. His open-source work spans developer experience and build tooling—contributions to microsoft/rushstack and fluentui show a cross-cutting fluency in TypeScript, React and build/release automation. Based in Singapore and currently on sabbatical, he brings a mix of enterprise-scale execution, developer-ecosystem thinking, and a knack for coaching the next generation of engineers. An understated strength is his track record of shipping durable solutions that scale organizationally, not just technically.
