Data Science Pipelines
ETL batch orchestration, Apache Airflow DAGs, feature engineering, Parquet columnar storage, Lakehouse architectures, and MLOps tracking.
Batch workflow scheduling, DAG dependency resolution, task state machines, retry policies, and atomic partition overwrite idempotency.
ETL Orchestration & Apache Airflow DAGs
Design resilient ETL pipelines using Apache Airflow, resolve task dependency graphs, and guarantee data idempotency.
Data leakage prevention, Fit-Transform hygiene, continuous feature scaling (Z-Score, Min-Max), and high-cardinality categorical target encoding.
Feature Engineering & Data Transformation
Construct leak-free feature preprocessing pipelines, apply numerical scaling, and encode categorical variables.
Modern Data Lakehouse design, Apache Iceberg ACID metadata snapshots, Parquet row groups, column projection, and predicate pushdown pruning.
Data Lakehouse & Columnar Storage (Parquet)
Architect modern Data Lakehouses, analyze Apache Parquet columnar storage internals, and accelerate queries via predicate pushdown.
MLOps lifecycle management, MLflow Tracking Servers, parameter and metric logging, Model Registry stage transitions, and Population Stability Index (PSI) drift monitoring.
MLOps - Model Tracking & Versioning (MLflow)
Implement end-to-end MLOps pipelines with MLflow, track experiment metrics, govern model registries, and detect production data drift.
