George Cheng

I’m a Senior Software Engineer with 10+ years of experience building scalable backend systems and data platforms, with strong expertise in Golang. I focus on writing efficient, reliable code that improves throughput, lowers latency, and keeps systems dependable in production.

At Audible, I designed and developed a distributed data ingestion platform in Go, processing high-volume streaming data from multiple sources. I built concurrent real-time pipelines with goroutines and channels, implemented REST and gRPC services, and delivered batch + streaming workflows using Kafka and Apache Spark (PySpark).

I also bring strong event-driven and data governance skills, including schema evolution strategies with Avro and Schema Registry. I integrated Python-based machine learning workflows (data preprocessing and feature generation), and built scalable storage and analytics services using Amazon S3 and Presto.

I’m proactive about quality and visibility: I implemented observability with Prometheus and Grafana, and improved reliability with unit and integration testing using the Go testing package and Testify. My impact includes ~30% improved pipeline throughput and ~25% reduced processing latency, and I’ve also improved API response times by ~20% and reduced message processing failures by ~15% at Oracle.
