Languages & Frameworks: Python is our core for pipelines, APIs, and CLI tooling. We use FastAPI and Pydantic to serve typed, high-performance REST APIs to our platform.
-
Data Transformation & Modeling: We use dbt for our SQL-based transformation layer and SQLModel with Alembic for ORM-based schema management and versioned migrations.
-
Storage & Analytics: Besides PostgreSQL / RDS, we utilize DuckDB and DuckLake as our embedded analytics engine, all hosted on a robust AWS infrastructure (S3, IAM).
-
Orchestration & Workflow: Apache Airflow handles our complex event-driven and scheduled job flows.
