Simplifying Data Pipelines
At ETLpi, we specialize in building robust and reliable ETL pipelines that power your business intelligence. From data extraction to final transformation, our solutions ensure your data is always ready for analysis.
Enterprise Data Engineering Services
We architect robust, auditable, and cost-efficient data platforms designed to scale seamlessly from gigabytes to petabytes.
Legacy Database Migration
Seamlessly migrate data off expensive legacy systems (Oracle, Teradata) to modern cloud warehouses like Snowflake, Databricks, BigQuery, or PostgreSQL with zero business disruption.
Metadata-Driven Ingestion
Eliminate manual pipeline scripting. We deploy automated, config-driven ingestion frameworks that onboard hundreds of tables dynamically using unified JSON and Excel rule schemas.
Slowly Changing Data Ingestion
We implement all Slowly Changing Dimension (SCD) patterns (Types 1, 2, 3, 4, and 6) with automated SCD Type 2 pipelines: built-in delta comparison, effective date tracking, and current record flag maintenance for strict audit and compliance needs.
PySpark & Compute Optimization
Tackle Out-Of-Memory (OOM) errors and sluggish batch jobs. We optimize distributed Spark partitions, broadcast joins, and caching to slash cloud compute bills by up to 50%.
Data Quality & Observability
Never let silent data bugs ruin executive dashboards. We integrate automated schema drift detection, anomaly alerting, and end-to-end pipeline health monitoring.
The ETLpi Config-Driven Ingestion Accelerator
Why spend 6 months hand-coding custom ETL scripts for every single table? Our production-tested framework enables data teams to onboard enterprise sources and manage complex transformations purely through unified JSON and Excel configs.
Multi-Source Connectors
Native, chunked extractors for Oracle, Teradata, PostgreSQL, MySQL, CSV, Excel, Parquet, and Cloud Storage.
Dual-Engine Power
Execute locally with Python/Pandas with zero JVM overhead, or scale to distributed PySpark clusters for terabyte-scale jobs without code rewrites.
Automated SCD Type 2 & All SCD Support
Full native implementation of all SCD types. Built-in delta comparison, effective date tracking, and current record flag maintenance for strict audit and compliance needs.
AI Rule Generation
Integrated Gemini AI to automatically generate field mappings and transformation logic, backed by human-in-the-loop review.
End-to-End Pipeline Architecture
We engineer robust data pipelines across sources, compute runtimes, cloud destinations, and orchestration layers.
Enterprise Extraction
Extracting structured relational tables and enterprise flat files with chunked streaming.
Distributed Processing
High-performance data transformation, schema validation, and memory-safe batch processing.
Modern Cloud Targets
Loading governed data marts, audit timelines, and analytical lakehouses.
Workflow Orchestration
Automated dependency scheduling, CI/CD containerization, and data drift monitoring.
