I build reliable data pipelines and AI systems for intelligent decision-making.
Sri LankaWhat I'm looking for
I build and maintain data pipelines powering pharmaceutical intelligence products at Gapstars, helping teams make faster, smarter decisions from life sciences data.
My work spans Airflow orchestration, Python ETL workflows, SQL, AWS S3, REST APIs, data quality, and production backend tooling. I take data from raw ingestion to structured, analytics-ready outputs while debugging complex DAG dependencies.
Previously, at LSEG, I developed log ETL pipelines with PostgreSQL and Grafana, automated Kudu validation with PySpark and Jenkins, and built Java-based validation suites.
I've also contributed to DistilGuard at NetsLab, developing federated learning simulations and LLM-based defenses for poisoning detection. I bring an analytical, creative approach to solving problems and learning as I go.
Experience
Work history, roles, and key accomplishments
