What I'm looking for

I’m seeking roles where I turn complex data into clear business value by owning data product strategy and delivery. With 6+ years in marketing/ad‑tech, I bridge product vision, data engineering, and analytics to drive measurable impact. Open to Data Architect, Analytical Engineer, or Data Owner roles to lead cross‑functional squads and deliver scalable, governed data products.

With 6+ years in Marketing and Advertising, I specialize in data-driven product development, translating business needs into scalable data solutions. As a Certified Scrum Product Owner, I bridge technical teams and stakeholders, driving product strategy for data-centric solutions. I have successfully led end-to-end projects, optimizing data pipelines, ETL workflows, and database architectures to power real-time analytics and revenue growth. Skilled in Python, Ruby, Java, MySQL, AWS Redshift, BigQuery, MongoDB, and Terraform, I deliver actionable insights that optimize performance and drive strategic decisions.

I excel in aligning product strategy with data engineering best practices, ensuring scalable, efficient, and business-relevant solutions.

Passionate about building impactful data products that drive business outcomes, I aim to continue creating solutions that enhance decision-making and operational efficiency
