Step-by-Step Guide
Follow along at your own pace. Most people finish in 2-4 months (for batch) / 6-12 months (for streaming).
Use Airbyte for batch data extraction
~10 minAirbyte is open-source and has 300+ pre-built connectors for databases, APIs, and SaaS tools. Self-host it with Docker or use their cloud service. For most batch ETL needs (daily or hourly syncs), Airbyte handles extraction without custom code. Set it up once and it runs reliably.
Transform with dbt
~15 minAfter Airbyte loads raw data into your warehouse, use dbt to clean and transform it. dbt runs SQL transformations on a schedule and handles dependencies between models. This is the 'T' in ELT and it's where most of the value is — turning raw data into business-ready tables.
Orchestrate with Dagster or Prefect
~15 minFor complex pipelines with dependencies, retries, and scheduling, use an orchestrator. Dagster has excellent observability and shows you exactly where failures happen. Prefect is simpler to get started with. Both have free tiers for small workloads.
Monitor pipeline health proactively
~20 minSet up alerts for pipeline failures, data freshness, and row count anomalies. Dagster and dbt both have built-in monitoring. At minimum, you need to know within an hour if a pipeline fails — stale data is worse than no data because people trust it and make decisions on outdated numbers.
When to hire instead
Hire when: you need real-time streaming pipelines (Kafka, Flink) instead of batch processing, you need custom API integrations that don't have pre-built connectors (legacy systems, proprietary APIs), your pipeline processes more than 1TB/day, or pipeline reliability is business-critical (e.g., financial data that feeds compliance reports where a missed sync means regulatory violations).
No time? Skip to hiringReal talk
For batch pipelines (syncing data from your SaaS tools to your warehouse daily or hourly), Airbyte + dbt handles 80% of use cases without writing custom code. Set it up in a weekend, and it runs reliably for months. Where it gets genuinely hard — and where you should hire — is real-time streaming (processing events as they happen), complex transformations that require domain expertise, and pipelines that need 99.9% reliability because downstream systems depend on them. If your data needs are 'sync Stripe + Salesforce + app database into BigQuery daily,' save your money and DIY it.
Tools You'll Need
Hand-picked for this project. We only recommend tools we'd actually use.
Essential Tools
You need these to get started.
VS Code
Free
Write pipeline code in Python with Airflow, Prefect, or Dagster. Extensions provide task graph visualization and debugging.
Why we recommend it
VS Code with Python extensions is the standard for data pipeline development — write, test, and debug orchestration code.
Claude Pro
$20/mo
