Hi, I’m Lahiru Nuwan—a Data Engineer passionate about turning complex data into scalable, reliable analytics. I design and operate cloud-based data platforms using AWS, Snowflake, Databricks, and Airflow to deliver production-grade pipelines, governed releases, and self-serve analytics. I enjoy collaborating with cross-functional teams to drive cost efficiency, data quality, and insight-driven decision making.
When I’m not building data solutions, I explore R&D opportunities, automate repetitive workflows, and share learnings with peers to help teams grow their capabilities and deliver impact faster.
