About me
I am an Engineering Lead and Cloud-Native Architect with deep experience designing and delivering high-performance distributed systems across banking, payment networks, cybersecurity, and defense. I specialize in translating complex business challenges into scalable, resilient architectures — from greenfield platforms to modernization of legacy systems handling millions of transactions daily.
As a technical leader, I have guided cross-functional engineering teams of 15+ engineers, established API-First design standards, and driven company-wide architectural governance. I bring hands-on depth in microservices, event-driven systems, cloud-native infrastructure on AWS, and modern data pipelines — alongside the strategic mindset to align engineering decisions with business outcomes.
I am a Certified AWS ML Engineer with active experience in AI/ML — including LLM orchestration, RAG pipelines, and AI-assisted development workflows. My stack spans GoLang, Java, Python, Spring Boot, Kafka, Kubernetes, and Terraform. I hold a Master's in Information Systems from Virginia Tech and a Bachelor's in Mechanical Engineering from Shanghai University.
