I’m a Data Engineer with hands-on experience building scalable data pipelines and warehouse solutions for major international clients across multiple countries. I focus on ETL development, performance tuning, and delivering reliable data access in complex, multi-stakeholder environments.
At Potenza (Pvt) Ltd, I led the development and maintenance of Azure pipelines to integrate diverse datasets into a centralized data warehouse, improving accessibility and reliability. I reduced daily pipeline failures and delays to achieve 95%+ on-time data delivery, designed ingestion frameworks for APIs and diverse sources to cut manual intervention by 30%, and partnered with global vendor teams to align with compliance and scalability requirements.
Previously at D P Infotech (Pvt) Ltd, I built impactful Power BI dashboards and supported 24/7 access for stakeholders, while helping migrate enterprise databases from Azure SQL to Microsoft Fabric to reduce query latency and improve performance. I also delivered automated dashboards and real-time KPI tracking using Grafana, and at Virtusa (Pvt) Ltd I developed onboarding and resource management dashboards and implemented scalable data pipelines using Azure Synapse Analytics, PySpark, and Data Lake.
