What I'm looking for

I seek roles where I can build scalable, cost-efficient data platforms and pipelines, mentor teams, and translate business needs into measurable analytics impact.

I am a Senior Analytics Engineer with a background in computer engineering and postgraduate training in business intelligence and data engineering. I lead strategic projects that deliver performance, scalability, and cost reductions by designing and refactoring high-performance data pipelines on cloud platforms.

I build and maintain data pipelines and orchestration using GCP, Dataform, Apache Airflow, and CI/CD practices, implement data quality checks and unit tests, and produce clear data models and documentation to ensure reliability and traceability. I also bridge data engineers and analysts, translating stakeholder requirements into robust technical solutions that drive business value.

I mentor and onboard team members, create playbooks and standards to scale delivery, and collaborate directly with cross-functional stakeholders to continuously improve processes and support strategic decision-making.
