Top SchoolRay Xian is a Senior Software Engineer based in Singapore with six years’ experience designing and optimizing large-scale microservices and low-level systems. He excels in system design, microservice architecture, and performance tuning across Go, C++, C#, and Python, with production familiarity in Kubernetes, Kafka, Redis, and cloud platforms (AWS/GCP). His recent roles at GetGo Carsharing show a fast trajectory from Software Engineer to Senior Engineer, delivering resilient, high-throughput services for real-world mobility systems. Ray combines practical REST/gRPC implementations with database expertise (Postgres, MongoDB, Elasticsearch) and a habit of squeezing extra performance through algorithm and data-structure refinement. He also brings teaching and research-adjacent experience from NUS (microarchitecture and programming methodology), which informs a disciplined, evidence-driven approach to code quality and observability. Colleagues value him for balancing system-level thinking with hands-on optimization that tangibly reduces latency and operational cost.
