Senior🎓
Top SchoolWu Lifu is a Head of Infrastructure based in Singapore with 12 years building high-scale cloud and backend systems for logistics and mapping platforms. He led teams at Grab to scale order and booking services to handle millions of daily transactions, then moved into platform and observability work at NextBillion.ai where he engineered performance-critical rewrites (Python to Rust) and custom gateway and telemetry tooling. His strengths span cloud infrastructure, realtime location services, API security (centralized key server with short-lived JWTs), and deploying ELK/Prometheus across Kubernetes clusters. Pragmatic and hands-on, he combines engineering leadership with deep systems-level coding—often replacing brittle components with lean, Rust- and Go-based services to squeeze out 10x improvements.
