Our AI Data Engineering system, powered by LLMs, dramatically accelerates pipeline generation. It integrates MLOps practices for reliable deployments. The system costs $25,000 to deploy and yields annual savings of $150,000. ETL pipelines for 15 heterogeneous sources (PostgreSQL, S3, Kafka) take 2–3 months of manual development. Profiling each source takes 3–5 days, and writing transformations takes another week. Our AI-powered ETL automation system dramatically accelerates pipeline generation. The LLM analyzes schemas, generates Python transformation code, quality rules, and DAGs for the orchestrator. Result: pipelines in hours, not months. With 7+ years in AI/ML and 30+ projects in fintech and retail, we guarantee a 5x reduction in ETL development time. Savings on FTE: one data engineer with the system replaces three, yielding annual salary savings of up to $150,000. Cloud resource costs drop up to 30% through optimized pipelines.
How AI-Generated ETL Code Cuts Development Time?
A typical project involves 10–30 sources with different formats. Manual profiling takes up to 75 days. The system automatically discovers and profiles sources, extracting schemas, statistics, and anomalies. Then, the LLM generates ETL code, quality rules, and DAGs — all within a single pipeline. Comparison: for 15 sources, manual profiling is 45–75 days; AI takes 4–6 hours. The model adapts code to source specifics, not just copy templates.

How We Integrate the System with Your Infrastructure?
We don't offer a boxed solution — every project is adapted to your stack. We start with an audit: which sources, how much data, which orchestrator (Airflow), which transformations (dbt). Then we tune the LLM prompts to your business rules. For example, for a retailer with custom discount calculation logic, we add few-shot examples to the prompt so the model generates correct code.
Example profiling of a PostgreSQL source
The system automatically connects to the database, extracts all tables, column types, row counts, null values, and uniqueness. The result is saved in JSON and fed to the LLM for transformation generation. This immediately identifies issues: for instance, if the price column has 10% NULL values, the model will propose handling.
