Dear Hiring Manager,

With 2 years of experience as an ETL Developer, I am excited to express my interest in the opportunity at your organization.

Currently serving as a Junior ETL Developer at Halliwell Corporation, I specialize in extracting, translating, and loading extensive data from SQL databases. My efforts in performance tuning and code enhancements have been acknowledged by senior management for contributing to the achievement of aggressive performance goals. Additionally, I have expertise in developing UNIX shell scripts for job scheduling, execution, and logging.

In addition to my hands-on experience, I hold a Bachelor's degree in Computer Science and possess certifications in ETL Framework for Data Warehouse Environments and SQL/ETL Developer - T-SQL/Stored Procedures/ETL/SSIS. My technical skill set includes proficiency in SQL, Bash, Python, Perl, Talend, Informatica, Pentaho, C++, and Java.

While I have valued my time at Halliwell, I am now seeking a senior ETL Developer role that offers opportunities for career advancement and the chance to contribute significantly to application design, development, and maintenance.

I have enclosed my résumé for your review. Thank you for considering my application. I eagerly anticipate the opportunity to discuss how my skills and experiences align with the needs of your team.

Sincerely,
William Basaj
