  2. ETL/ELT Pipeline Engineering and Orchestration

    4 weeks
    Goals
    • Build production-grade ETL pipelines using Apache Airflow or Dagster
    • Implement incremental loading, schema evolution handling, and idempotent transformations
    • Apply data quality frameworks like Great Expectations to validate pipeline outputs
    Resources
    • Apache Airflow official documentation and tutorials
    • Dagster University free course
    • Great Expectations documentation and example notebooks
    • Data Engineering Zoomcamp by DataTalksClub (free)
    Milestone

    You can build an end-to-end automated pipeline that extracts data from APIs, transforms it through staging layers, and loads curated models into a warehouse with data quality checks.

  3. LLM Integration and AI Agent Fundamentals

    4 weeks
    Goals
    • Understand LLM APIs, prompt engineering patterns, and structured output generation
    • Build basic AI agents using LangChain and LangGraph that can generate and execute SQL
    • Implement function-calling patterns where LLMs invoke database operations safely
    Resources
    • LangChain official documentation and quickstart guides
    • LangGraph conceptual guides for agent state machines
    • OpenAI Cookbook for SQL generation and function calling
    • DeepLearning.AI short courses on LangChain and AI Agents
    Milestone

    You can build an AI agent that takes a natural language data requirement, generates appropriate SQL transformations, validates the output, and executes it against a warehouse.

  4. Warehouse Automation Architecture and Production Systems

    4 weeks
    Goals
    • Design multi-agent systems for end-to-end warehouse automation (extraction, modeling, validation, documentation)
    • Implement human-in-the-loop approval workflows for AI-generated schemas and transformations
    • Build CI/CD pipelines for database schema changes, transformation code, and AI prompt versioning
    Resources
    • Building LLM Applications with LangGraph (Advanced)
    • Terraform for Snowflake or BigQuery provider documentation
    • GitHub Actions documentation for CI/CD pipeline design
    • Papers and blog posts on DataOps and Data Mesh automation
    Milestone

    You can architect a production-grade AI-powered data warehouse automation system with governance controls, rollback capabilities, and continuous improvement feedback loops.

  5. Specialization, Cost Optimization, and Thought Leadership

    4 weeks
    Goals
    • Master warehouse cost optimization techniques including query profiling, clustering keys, and workload management
    • Develop domain-specific automation patterns for regulated industries (healthcare, finance)
    • Build a portfolio project and begin contributing to open-source data automation tooling
    Resources
    • Snowflake and BigQuery cost optimization guides and best practices
    • Open-source data automation projects on GitHub for contribution
    • Industry conferences recordings (dbt Coalesce, Snowflake Summit, Data Council)
    • Technical blog writing and portfolio development
    Milestone

    You can lead the design of an enterprise AI data warehouse automation practice, mentor junior engineers, and present technical solutions to stakeholders.

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

AI-Powered Schema Generator

Beginner

Build a Python application that uses OpenAI's API to automatically generate star schema DDL (fact and dimension tables) from a provided entity-relationship description or source DDL. The tool should output valid SQL for a chosen warehouse dialect (Snowflake or BigQuery) and include basic naming convention enforcement.

Prompt engineering for SQL generationDimensional modeling conceptsPython API integration

Automated ETL Pipeline with AI Data Quality Checks

Intermediate

Build an end-to-end ETL pipeline using Airflow that extracts data from a public API, loads it into a staging area, transforms it into a star schema using dbt, and integrates AI-powered data quality checks where an LLM analyzes Great Expectations validation results and produces human-readable summaries of data issues.

~40h
Airflow DAG design and schedulingdbt model development and testingGreat Expectations configuration

LangChain SQL Agent for Self-Service Data Warehouse Querying

Intermediate

Create a conversational AI agent using LangChain that allows business users to ask natural language questions and receive accurate SQL queries executed against a data warehouse. Implement safety guardrails including read-only access, query complexity limits, and result formatting for non-technical users.

LangChain agent designFunction calling and tool useSQL safety and access control

Multi-Agent Warehouse Automation Pipeline

Advanced

Design and implement a LangGraph-based multi-agent system where separate AI agents handle source profiling, schema design, transformation generation, test creation, and documentation. Each agent has a defined role, passes structured outputs to downstream agents, and includes human-in-the-loop checkpoints for critical decisions like dropping or altering production tables.

LangGraph multi-agent orchestrationStructured output parsing and validationHuman-in-the-loop workflow design

Legacy-to-Cloud Warehouse Migration Automator

Advanced

Build a tool that ingests DDL and sample data from a legacy Oracle or SQL Server warehouse, uses AI to translate schemas and stored procedures to Snowflake or BigQuery dialect, generates automated reconciliation queries to validate data parity between old and new systems, and produces a migration runbook with risk assessments for each object.

~50h
SQL dialect translationLegacy database system understandingAutomated reconciliation testing

Self-Healing Pipeline Monitor with AI Root Cause Analysis

Advanced

Create an automated monitoring system that watches Airflow or Dagster pipeline runs, detects failures, uses an LLM to analyze error logs and metadata to identify root causes, suggests or auto-applies fixes (e.g., retry with adjusted parameters, schema update, dependency resolution), and logs all actions for audit and learning purposes.
