Most engineering teams don't struggle with individual tools - they struggle with system reliability at scale. True Data Engineering builds pipelines that survive schema changes, platforms that handle traffic spikes gracefully, and architectures that evolve without breaking existing workflows. At Fornax, we engineer data systems that combine performance, reliability, and maintainability into infrastructure that scales predictably.

Our approach focuses on engineering fundamentals: idempotent pipelines that handle retries safely, monitoring that catches issues before users notice, and abstractions that reduce cognitive load for development teams. We design systems that handle the messy reality of production data while maintaining clean interfaces for consumers. The result: data infrastructure that enables continuous deployment, handles failure gracefully, and provides the foundation for real-time analytics and ML workloads that actually work in production.

What engineering teams ask us

How do we build pipelines that don't break when schemas change?

What's the right pattern for handling late-arriving and out-of-order data?

How do we manage backfill and reprocessing without downtime?

How do we test data pipelines and ensure data quality in CI/CD?

What's the best way to handle streaming vs. batch for different SLAs?

What you get

Pipeline Architecture

Event-driven, idempotent data workflows with proper error handling, dead letter queues, and automatic retry logic.

Stream Processing Framework

Real-time pipelines using Kafka, Pulsar, or cloud-native streaming with exactly-once semantics and windowing strategies.

Data Quality Engineering

Automated testing, schema validation, and data contracts with continuous monitoring and alerting.

Frequently Asked Questions

How do we structure dbt projects for multiple teams and domains?

Use dbt's package system with separate projects per domain connected through dbt hub or git submodules. Implement shared macros and testing standards through internal dbt packages. Use Snowflake's database/schema structure to isolate environments and enable cross-team data sharing through well-defined marts.

What's the best orchestration tool for modern data stack workflows?

Dagster excels for complex data lineage and testing integration with dbt. Prefect offers great developer experience and dynamic workflows. Airflow works well if you need extensive operator ecosystem. Choose based on team preferences and complexity - most modern stacks work well with any of these when properly configured.

How do we manage costs across Snowflake, Databricks, and SaaS tools?

Implement usage-based alerting in Snowflake with automatic warehouse suspension. Use Databricks cluster policies and auto-termination. Monitor SaaS tool usage through APIs and set up budget alerts. Tag resources consistently for cost allocation and use tools like Vantage or CloudZero for unified cost monitoring.

What's the right testing strategy for dbt transformations?

Implement dbt tests at source (freshness, uniqueness), staging (not null, relationships), and mart layers (business logic validation). Use dbt-expectations for advanced statistical tests. Run tests in CI/CD with proper test data management. Combine with Great Expectations for runtime data quality monitoring.

How do we handle schema changes across Fivetran, Snowflake, and dbt?

Enable Fivetran's schema drift handling with alerts. Use dbt's source freshness and schema tests to detect changes early. Implement dbt snapshots for SCD handling. Design dbt models to be resilient to new columns using select * exclude patterns and proper source definitions with descriptions.
