SQL

Build and deploy this Next.js presentation application with PostgreSQL database. Use when building, deploying, setting up database, or preparing the project for production. Triggers on requests to build, deploy, seed database, or publish.

FastAPI with PostgreSQL, async SQLAlchemy 2.0, Alembic, and Docker.

Run DuckDB SQL queries over CSV, Parquet, JSON/NDJSON, Excel (.xlsx), and database sources (Postgres, MySQL, SQLite, S3) for data exploration and analytics. Use when the user wants to: (1) Explore, filter, or aggregate data from tabular files, (2) Join multiple datasets, (3) Perform analytical SQL over local files or databases, (4) Get precise numeric/statistical results from large datasets. Prefer this over in-context reasoning for datasets with thousands of rows or complex joins/aggregations.
