Cheng Du is a systems-focused software engineer with 10 years' experience designing real-time, high-performance systems across embedded, backend, and web domains. He has led fraud-detection and dynamic incentive systems at Gojek and Grab, optimized MySQL round-trips and rebuilt end-to-end testing at Meta for a WhatsApp Enterprise client, and contributed performance and UI improvements to the high-throughput HTTP benchmark plow. Passionate about what's "close to the metal," Cheng explores Linux kernel/device drivers, GPU shader programming, DSP and concurrent embedded code in side projects such as WebGL Mandelbrot and Fourier visualizers. Equally comfortable in C++, Go and full-stack work, he blends low-level curiosity with product-facing delivery at scale. Based in the UK, he pairs hands-on coding with a track record of pragmatic systems engineering and tooling that improves observability and real-time behavior.
