FAQ
A What do you need from me before starting?
A description of the problem, your current data sources and destination, and any relevant code, schemas or API documentation. For larger projects, please message me before ordering so we can agree the scope.
Can you fix an existing pipeline rather than build a new one?
Yes. I can troubleshoot Python, SQL, PySpark, Databricks, Azure Data Factory and related ETL pipelines, identify the cause of an issue and implement a fix.
Which data sources can you work with?
I can work with REST APIs, SQL databases, PostgreSQL, SQL Server, files such as CSV/JSON/Parquet, data lakes and other common sources. Message me if you have a less common system.
Can you optimise a slow or expensive pipeline?
Yes. I can review the architecture and code, identify bottlenecks and improve areas such as transformations, Spark processing, data layout, parallelism and unnecessary compute.
Can you work with Databricks and Azure?
Yes. Databricks and Azure data engineering are core areas of my professional experience, including PySpark, Delta Lake, Azure Data Factory, ADLS and SQL-based platforms.
Should I contact you before ordering?
For the Basic package, a clearly defined small task can usually be ordered directly. For Standard, Premium or anything where the scope is uncertain, please message me first.
