HAFIZ ABDUL MANNAN
I am a Certified Data Management Professional (CDMP-DAMA), AWS Certified Data Engineer, and Oracle 19c OCP DBA with over 20 years of international experience in data engineering, cloud architecture, enterprise data governance, and strategic leadership of data services. Throughout my career, I have successfully delivered end-to-end scalable, secure, and cost-optimized data platforms, aligning business strategy with technical execution to achieve measurable, data-driven outcomes.
I specialize in architecting and modernizing multi-cloud data ecosystems (AWS, Azure, GCP, OCI) capable of managing both structured and unstructured data at petabyte scale. My expertise covers SQL (Oracle, PostgreSQL, SQL Server, MySQL), Python, Spark, Airflow, and real-time streaming platforms such as Kafka and Kinesis. I have delivered more than 492 ETL/ELT pipelines and 700+ BI dashboards across Tableau, Power BI, MicroStrategy, and Oracle Analytics Cloud. In addition, I have led 300+ zero-downtime database migrations and deployed 100+ RAC/Data Guard rollouts.
Through advanced optimization, automation, and compression techniques, I have achieved up to 60% cloud cost reductions and more than 50% SQL performance improvements. I also provide strategic advisory in enterprise data governance, metadata management, and regulatory compliance (GDPR, HIPAA, SOC 2, CISSP), leveraging DAMA-aligned frameworks, enterprise catalogs, and robust data quality standards.
Beyond technical delivery, I have conducted 20+ global Oracle training workshops and led cross-functional teams of up to 50 professionals, applying Agile, TOGAF, and ITIL frameworks. I am known for my ability to bridge executive vision with technical implementation, consistently delivering large-scale, secure, and future-ready data ecosystems.
