Julia Chou

I am a senior backend engineer with a decade of experience building distributed systems, scalable APIs, and production-grade infrastructure in high-growth fintech environments. I focus on system architecture, performance optimization, and secure service design.

At Coinbase, I designed and deployed a distributed auction price discovery service that increased market opening efficiency by 25% and improved throughput under peak load. I engineered advanced limit order book logic to support over 12,000 active orders with real-time state syncing and high-availability guarantees.

I have a strong track record of scaling backend systems to support a threefold increase in trading volume by optimizing latency-sensitive services with Redis caching, asynchronous job queues, and horizontal autoscaling. I also implemented geofencing logic that reduced unauthorized access by 40% and built internal APIs that cut asset onboarding time by 35%.

Beyond fintech, I migrated job infrastructures to Sidekiq achieving a 350% throughput gain, decomposed monoliths into services, integrated monitoring and alerting (Prometheus, Grafana, ELK), and contributed to security automation and incident response improvements. I enjoy bridging product goals with engineering clarity and driving platform scalability and operational resilience.
