👨‍💻 About Me

Senior Software Engineer · Full-Stack Builder · Cloud & Performance Enthusiast

I'm a software engineer with 10+ years of experience building and improving production systems, including work at Netflix, AWS, and Cisco.

I enjoy the engineering details that make products dependable: tracing slow database queries, designing clear APIs, scaling asynchronous workflows, and making deployments repeatable. I use Claude Code, Cursor, and GitHub Copilot to accelerate development, while keeping architecture, validation, and code review firmly in human hands.
