Big Data Sales Jobs

I need an experienced specialist who can take raw information from multiple sources, shape it into a clean, reliable dataset, and then turn that into clear, decision-ready insights. You should be equally comfortable writing repeatable extraction scripts, performing statistical analysis, and presenting the findings in an easy-to-digest format. The work will involve: • Securely pulling data from the sources I provide • Cleaning, normalising, and validating everything so it is analysis-ready • Running the agreed analytical models or exploratory techniques • Packaging the results in a concise summary report and, where useful, visual dashboards I generally rely on Python (pandas, NumPy, matplotlib, seaborn), SQL, and Excel for ad-hoc checks, but I’m open to...

I’m sitting on a large database that stores semi-structured records, and I need a robust transformation layer that turns this raw content into analysis-ready tables. The data is already captured and stored; the task begins once the records land in the database and ends when the transformed results are written back to a target schema (or files, if that proves more efficient). Key points you should know • Source: relational database containing nested JSON / key-value blobs. • Goal: parse, normalize, and flatten these blobs into well-defined columns while preserving relationships and lineage. • Scale: millions of rows, so solutions that leverage Spark, Hadoop, BigQuery, Snowflake, or well-tuned SQL/Python pipelines are welcome—as long as they remain maintaina...
