Andrew Lynas

With extensive experience as a Senior Data Engineer, I specialize in designing, building, and optimizing data pipelines, automating workflows, and ensuring high data quality. My skill set includes advanced proficiency in SQL, Python, GCP, Apache Airflow, DevOps practices, and data visualization tools like Tableau.

I have a proven track record of driving performance optimizations that reduce runtime (e.g., reducing a process from over 7 hours to just 15 minutes) and enhancing data quality through rigorous testing, including SQL assertions and unit tests. My work spans from collaborating with data scientists and stakeholders to delivering tailored solutions that meet business needs, to implementing automated monitoring and alerting systems that have significantly reduced downtime.

I am passionate about leveraging cloud technologies, particularly Google Cloud Platform (GCP), to build scalable and reliable data architectures that empower businesses with data-driven insights. As a freelancer, I am committed to providing innovative solutions and helping clients achieve their data goals through collaboration, technical expertise, and a focus on results.
