Hafiz Suleman

I am a Senior Data Engineer and Data Architect with 9+ years designing and delivering cloud data platforms on Snowflake, Databricks, AWS and Azure, backed by a strong software engineering and database background.

I specialize in Medallion (Bronze/Silver/Gold) lakehouse design, CDC pipelines and scalable ELT/ETL workflows using Python, PySpark, SQL, dbt and Apache Airflow. I also tune Snowflake and Spark for performance and cost, and I have recently built RAG ingestion pipelines using vector embeddings.

Key achievements:

- Improved data processing performance by 40% by designing cloud-native AWS data architectures for enterprise clients (Northbay Solutions)

- Cut a critical Spark job from 45 to 20 minutes for a European telecom client by tuning PySpark and Spark SQL in Databricks (Confiz)

- Migrated a 10 TB Oracle database to Amazon RDS for PostgreSQL and led other Oracle and SQL Server migrations to AWS and Azure (Northbay Solutions)

- Led client projects from pre-sales discovery and solution design through to delivery across AWS and Azure (Indatalabs)

I have led teams of up to 12 engineers and worked directly with product teams in the US, Europe and Australia. I am comfortable turning business needs into clear technical designs and explaining them to non-technical stakeholders. My domain experience covers healthcare, telecom and education.

Certifications: AWS Certified Data Engineer - Associate and Snowflake SnowPro Core.

I am based in Pakistan and work fully remotely, with overlap with US and EU hours. I am open to full-time remote roles or long-term B2B contracts.
