Design, build, and maintain high-performance data processing pipelines using Python libraries (Pandas, Polars).

Develop and expose RESTful APIs using FastAPI or similar frameworks.

Consume and process normalized Parquet files from multiple upstream sources to generate dynamic Excel reports.

Contribute to a spec-driven development workflow (using GitHub Copilot, Claude, etc.) to scaffold and generate API / data pipeline code.

Optimize report generation logic for speed and scalability, currently targeting sub-20 second response times.

Integrate with messaging and storage mechanisms (e.g., Service Bus, Storage Accounts).

Collaborate on infrastructure-as-code automation using Bicep (or similar IaC tools).

Participate in design discussions for future migration to Snowflake and / or a data lake architecture.

Contribute to CI / CD pipelines using GitHub Actions.
