Building Custom Neural Networks from Scratch with PyTorch

Pre-built neural network architectures serve most deep learning needs, but understanding how to build custom networks from scratch unlocks true mastery of PyTorch and enables you to implement cutting-edge research, create novel architectures, and deeply understand what happens during training. While using nn.Sequential or standard layers is convenient, building networks from the ground up reveals … Read more

Real-Time CDC Data Pipeline Using Airflow and Postgres

Building a Change Data Capture (CDC) pipeline with Apache Airflow and PostgreSQL creates a powerful data integration solution that balances real-time requirements with operational simplicity. While Airflow is traditionally known for batch orchestration, its extensible architecture and support for sensors, custom operators, and dynamic DAG generation make it surprisingly capable for near real-time CDC workloads. … Read more

CDC Data Pipeline with Databricks and Delta Lake

Change Data Capture (CDC) pipelines built on Databricks and Delta Lake represent a paradigm shift in how organizations handle real-time data integration. Unlike traditional ETL approaches that rely on scheduled batch processing, a CDC pipeline continuously captures and processes database changes as they occur, enabling near real-time analytics and operational insights. Delta Lake’s ACID transaction … Read more

CDC Data Pipeline on AWS: S3, Glue, and Redshift Integration Example

Change Data Capture (CDC) pipelines on AWS have become the backbone of modern data warehousing strategies, enabling organizations to maintain near real-time analytics capabilities without overwhelming source databases. By combining Amazon S3 as a data lake, AWS Glue for transformation and cataloging, and Amazon Redshift for analytics, you can build a scalable CDC pipeline that … Read more

Building a CDC Data Pipeline with Debezium and Kafka

Change Data Capture (CDC) has become an essential pattern for modern data architectures, enabling real-time data synchronization between systems without the overhead of batch processing or manual data extraction. When you need to capture database changes and stream them reliably to downstream consumers, combining Debezium with Apache Kafka creates a powerful, production-ready solution. This article … Read more

Numpy for Machine Learning: Essential Tools for Data Engineers

NumPy stands as the foundational library for numerical computing in Python and serves as the backbone of the entire machine learning ecosystem. For data engineers building ML pipelines, preprocessing data, or implementing custom transformations, mastering NumPy’s capabilities is not optional—it’s essential. This guide explores the NumPy operations and patterns that data engineers encounter daily when … Read more

Deploying Machine Learning Models Using FastAPI

Moving machine learning models from Jupyter notebooks to production systems represents a critical transition that many data scientists struggle with. While you might have a model that achieves impressive accuracy on test data, that model provides zero business value until it’s accessible to applications, users, or other systems. FastAPI has emerged as the go-to framework … Read more

How to Implement a CDC Data Pipeline in Snowflake Using Fivetran

Change Data Capture (CDC) has become essential for modern data architectures that require real-time or near-real-time data synchronization. Rather than replicating entire tables repeatedly, CDC identifies and captures only the changes—inserts, updates, and deletes—dramatically reducing data transfer volumes and enabling incremental updates. Fivetran simplifies CDC implementation by handling the complexity of log-based replication, transformation, and … Read more

Building a Scalable PySpark Data Pipeline: Step-by-Step Example

Building data pipelines that scale from gigabytes to terabytes requires fundamentally different approaches than traditional single-machine processing. PySpark provides the distributed computing framework necessary for handling enterprise-scale data, but knowing how to structure pipelines for scalability requires understanding both the framework’s capabilities and distributed computing principles. This guide walks through building a complete, production-ready PySpark … Read more

Building an ETL Pipeline Example with Databricks

Building an ETL pipeline in Databricks transforms raw data into actionable insights through a structured approach that leverages distributed computing, Delta Lake storage, and Python or SQL transformations. This guide walks through a complete ETL pipeline example, demonstrating practical implementation patterns that data engineers can adapt for their own projects. We’ll build a pipeline that … Read more
