Software Engineer / DevOps Engineer

I'm a senior software engineer with a DevOps focus and a strong full-stack background. I build reliable systems end to end, from designing web applications and RESTful APIs to automating infrastructure as code, running zero-downtime CI/CD pipelines, and operating scalable, well-monitored cloud platforms.
