I'm writing to apply for the DevOps Engineer position at [Company]. With 5 years of experience building CI/CD pipelines and managing cloud infrastructure, I've helped teams ship faster while maintaining reliability and security.

At my current company, I reduced deployment time from 2 hours to 15 minutes by implementing automated pipelines with GitHub Actions and Kubernetes. I also designed our multi-region AWS infrastructure, achieving 99.95% uptime and reducing cloud costs by 40% through right-sizing and spot instances. I've led incident response for critical outages and established runbooks that decreased MTTR by 60%.

I'm passionate about enabling developer productivity through automation and would love to bring this expertise to [Company]. I look forward to discussing how I can strengthen your infrastructure.
