Hey, I'm Chenyan 👋

I'm a Software Engineer passionate about building scalable cloud infrastructure and creating full-stack applications that can handle real-world traffic. I work with both AWS and GCP to design cloud-native solutions, and I also build agentic AI systems using the Claude API and Google Gemini.

I believe in Infrastructure as Code, automated deployments, and making systems that don't wake you up at 3 AM. Let's build cloud architecture that scales effortlessly.

🎯 What I Do

• 💻 Software Engineering: Build full-stack applications with modern frameworks and best practices
• ☁️ Multi-Cloud Architecture: Design and deploy production-ready infrastructure on AWS and GCP
• 🔄 DevOps & CI/CD: Build automated pipelines that take code from commit to production with zero downtime
• 🏗️ Infrastructure as Code: Terraform everything - VPCs, databases, compute, networking, security groups
• 📊 Monitoring & Observability: Set up comprehensive logging and metrics so you always know what's happening
• 🔐 Security First: Implement IAM best practices, encryption at rest and in transit, and proper network isolation
• 🤖 Agentic AI: Build AI agents that reason, use tools, and take action — not just chatbots
