@irenechang
Senior software engineer specializing in scalable SaaS platforms and distributed systems.
United StatesWhat I'm looking for
I am a Senior Software Engineer with 14+ years building enterprise SaaS platforms, high-availability distributed systems, and cloud-native infrastructure. I design and deliver scalable frontend and backend solutions that improve reliability and latency at global scale.
At Slack/Salesforce I led full-stack development of fault-tolerant messaging and channel services, implemented distributed event-driven microservices in Java and Kotlin, and reduced p95 latency by 25% under peak traffic. I also built real-time pipelines with Kafka and high-performance React/TypeScript components for the web client.
Previously at AppDynamics and Workday I architected high-throughput metrics ingestion pipelines, analytics services for anomaly detection, and core backend services for enterprise HR and monitoring platforms. I migrated monoliths to Kubernetes, implemented CI/CD, and improved observability with Prometheus, Grafana, and OpenTelemetry.
I prioritize operational excellence, security, and scalability—integrating OAuth2/SSO, cloud KMS, and compliance alignment (SOC2, GDPR). I collaborate across product, QA, and platform teams to deliver resilient systems and measurable performance improvements.
