Data Steward | Data Quality & Governance | ETL/ELT Pipelines

Hello everyone, I’m Syahman, a Data Quality Specialist dedicated to building reliable, error-free data ecosystems. Coming from a background in rigorous Data Stewardship, I understand that bad data leads to bad business decisions. I specialize in programmatic data cleansing, automated validation, and building resilient data architectures that businesses can actually trust. How I bring value to your data: - Programmatic Data Cleansing: Using advanced SQL to standardize messy, real-world datasets. - Data Transformation & Modeling: Building clean, heavily-tested dimensional models and join spines using dbt. - Workflow Orchestration: Automating data extraction and validation processes using Apache Airflow and Docker. - Data Governance & Auditing: Engineering automated anomaly-detection tables to continuously monitor data integrity. I transform chaotic databases into structured, high-quality assets that drive operational efficiency. If you are looking for an engineer who cares deeply about the accuracy of your data, let's collaborate.
