Back-End Developer Sample Cover Letter

Dear Hiring Manager,

I am writing to apply for the Back-End Developer position at your company. With four years of experience building scalable server-side applications and APIs, I bring strong proficiency in Node.js, Python, and PostgreSQL, and a deep commitment to writing clean, maintainable code.

In my current role, I architected and maintained a RESTful API serving 2 million daily requests with 99.95% uptime. I have experience with microservices architecture, containerisation using Docker and Kubernetes, and CI/CD pipelines in GitHub Actions.

I am eager to contribute to your engineering team and help build robust back-end systems that scale. I look forward to discussing the opportunity in more detail.

Yours sincerely,

Robin Park
