I’m applying for the Junior Data Engineer position at dbt Labs. After spending the last few years building reliable data pipelines, I’m drawn to the opportunity to bring that experience to a company that’s shaping how the industry works.
At my current role, I built my capstone project as a complete ELT pipeline using dbt, Airflow, and BigQuery that processed 3 years of public transit data and powered a dashboard used by city planning researchers. This wasn’t just a technical win — it changed how our team operates and directly impacted the business.
Beyond that, I during my internship, I fixed a data quality issue in a production pipeline that had been silently dropping 4% of records for weeks, implementing a validation framework that caught similar issues automatically going forward. These experiences taught me that the best work happens when technical execution meets clear thinking about what matters to users and the business.
I’d welcome the chance to discuss how my experience in data modeling with dbt and SQL could contribute to your team. I’m available for a conversation anytime.
