I'm leading SadaPay's data platform as a single-contributor data engineering function, owning architecture, ingestion, analytics infrastructure, and reporting across business domains. I migrated the full data estate from Bahrain to Frankfurt with minimal downtime and zero data loss.

I've built audit-ready pipelines for 12M+ financial transactions and validation workflows for a $5M+ refund initiative affecting 500K+ customers. My work also includes secure delivery infrastructure for millions of tax documents and analytics systems that support regulatory, tax, and operational reporting.

Previously, I engineered cloud-native financial data platforms at SadaPay and Bazaar, including AWS-based analytics infrastructure serving 2,000+ users and 100,000+ SQL queries per day. I build distributed ETL and streaming pipelines with PySpark, Kafka, Airflow, Redshift, AWS, and Kubernetes.

I've also delivered document intelligence, AI analytics, backend, and data-processing platforms for Neste, EnerGPT, SymposAI, and DilmunPay, translating complex operational needs into dependable production systems.
